Allegiant Air Pilot Financial Planning: Match-Based 401(k), the Nevada Tax Edge, and What the Sun Country Merger Means for Retirement

Allegiant Air pilots fly a leisure-focused, point-to-point operation from a Las Vegas hub — and that operational profile creates a financial planning picture structurally different from both mainline network carriers and most other low-cost operators. The differences run deep: the 401(k) is match-based rather than the non-elective contribution structure that dominates at mainline carriers, which changes the planning math in ways most pilots haven't fully modeled. Nevada's zero state income tax, a permanent feature of the Las Vegas domicile, is worth $15,000–$25,000 per year to a senior Allegiant captain compared to peers based in high-tax states. And the May 2026 completion of Allegiant's acquisition of Sun Country Airlines — combining approximately 2,100 pilots from two distinct compensation structures under one corporate roof — introduces contract and seniority integration uncertainty that every Allegiant pilot needs to understand before finalizing retirement projections.

This guide covers the mechanics of Allegiant's retirement plan and how the match structure changes your §415(c) math, the Nevada domicile advantage and how to protect it, what no defined-benefit pension means for disability planning, and what the Sun Country integration means for your benefits trajectory.

Allegiant Air retirement system at a glance (2026):

401(k) structure: Match-based — the company contributes when you contribute. Under the Teamsters Local 2118 CBA (under active renegotiation in 2026), pilots who contribute 5% of eligible pay receive a company match of approximately 10% of eligible pay, for a total of roughly 15% of pay going into the 401(k) when pilots hit the contribution threshold. Verify the current rate with your union rep, as a successor agreement was in negotiation at time of writing.¹
Critical difference from mainline NEC: Unlike Delta (18% MBCBP NEC), United (18% PRAP NEC), or Southwest (18% NEC), Allegiant's employer contribution is not unconditional. If you contribute nothing, the company deposits nothing. At mainline carriers, the NEC deposits regardless of whether you elect any deferrals.
Traditional defined-benefit pension: None. Allegiant has never established a DB pension plan. Retirement security depends entirely on 401(k) accumulation and personal savings.
Profit sharing: Variable; tied to Allegiant operating results. Paid as ordinary W-2 income — not deposited into the 401(k). Do not build it into your base retirement projection.
Contract status: Allegiant pilots have been represented by the International Brotherhood of Teamsters Local 2118 since 2016. Negotiations for a new CBA were ongoing in 2025–2026, with pilots conducting informational pickets in late 2025. A new contract had not been ratified as of mid-2026.²

Match vs. NEC: the structural difference and why it matters

The distinction between a match-based 401(k) and a non-elective contribution (NEC) program shapes three different planning dimensions for Allegiant pilots.

1. You must contribute to collect. At Allegiant, a pilot enrolled with a 0% deferral rate receives zero company retirement contributions. At a mainline carrier with an 18% NEC, the company deposits regardless of the pilot's election. An Allegiant pilot who opts out — perhaps to maximize take-home during lean years — forfeits tens of thousands in company contributions that will never be recovered. The single most important action for every new Allegiant hire is to set the 401(k) contribution to at least the match trigger threshold from day one of eligibility.

2. The bucket fills differently. At mainline carriers, the employer's large NEC pre-occupies most of the §415(c) annual additions bucket early in the year. A Delta or United captain above $300,000 may see the company NEC consuming $48,000–$54,000 of the $72,000 limit before adding a single personal dollar. Allegiant's smaller company match (approximately $9,000–$36,000 at typical FO through captain compensation) leaves substantial room for personal deferrals. See the §415(c) section below for the full math.

3. Leaves and furloughs have direct impact. If the company contribution is tied to your pay and your contributions, any period without pay — furlough, unpaid leave, medical grounding — means the company deposit also stops. Allegiant pilots in a furlough scenario should immediately review the Furlough Financial Planning guide for account protection steps including 401(k) rollover decisions and COBRA timing.

The §415(c) math: no squeeze at Allegiant income levels

The IRS §415(c) limit caps all annual additions to a defined-contribution plan — employer contributions plus employee deferrals — at $72,000 in 2026. The §401(a)(17) limit caps the compensation recognized for plan calculations at $360,000 in 2026.³

At Allegiant's income and contribution structure, no pilot reaches the §415(c) ceiling. The company's maximum contribution — approximately 10% of $360,000 capped comp = $36,000 — leaves $36,000 available for personal deferrals before the limit is reached. Since the 2026 employee elective deferral limit is $24,500 (or $32,500 with age-50 catch-up; $35,750 for ages 60–63 super catch-up), an Allegiant pilot can contribute the full personal deferral at any income level without hitting the ceiling.

Pilot scenario	Eligible comp	Company contribution (~10%)	§415(c) room remaining	Max employee deferral	Total 401(k)
First officer, $90K	$90,000	$9,000	$63,000	$24,500 (full)	$33,500
First officer, $150K	$150,000	$15,000	$57,000	$24,500 (full)	$39,500
Junior captain, $200K	$200,000	$20,000	$52,000	$24,500 (full)	$44,500
Captain, $250K	$250,000	$25,000	$47,000	$24,500 (full)	$49,500
Senior captain, $290K	$290,000	$29,000	$43,000	$24,500 (full)	$53,500
Same, age 50+ catch-up	$290,000	$29,000	$43,000	$32,500	$61,500
Same, age 60–63 super catch-up	$290,000	$29,000	$43,000	$35,750	$64,750

The absence of a squeeze is a genuine planning advantage — no annual recalculation of how much deferral room the NEC leaves inside the bucket. The planning simplicity comes at the cost of a smaller total ceiling: Allegiant pilots max out at approximately $64,750 per year for the highest-paid captain in the super catch-up window, versus $80,000+ for a senior captain at a mainline carrier with an 18% NEC and the same catch-up provisions.

Catch-up contributions ($8,000 for age 50+) and the ages 60–63 SECURE 2.0 super catch-up ($11,250) sit outside the §415(c) annual additions limit — they add on top rather than consuming space within it.³ Under SECURE 2.0 § 603, pilots who earned more than $145,000 in prior-year wages must make 2026 catch-up contributions as Roth — traditional pre-tax catch-up is not permitted for these earners. This applies to virtually all Allegiant captains and most senior first officers.

Backdoor Roth and the pro-rata trap

Allegiant captains typically exceed the Roth IRA direct contribution phase-out for married-filing-jointly ($236,000–$246,000 in 2026).³ The backdoor Roth — non-deductible traditional IRA contribution converted immediately — remains available regardless of income, adding $7,000 ($8,000 if age 50+) in Roth accumulation annually. With no non-qualified overflow vehicle at Allegiant, this annual Roth addition is more valuable than it might appear at mainline carriers that automatically deposit excess above §415(c) into a supplemental plan.

The pro-rata rule is the trap. If you hold pre-tax IRA balances — rollover IRAs accumulated during regional FO years, or deductible contributions from lower-income years — those balances are aggregated when calculating the taxable fraction of a Roth conversion. A $100,000 rollover IRA turns the backdoor Roth into a largely taxable event. The fix: confirm whether the Allegiant 401(k) plan document accepts incoming rollover IRA contributions. If it does, move the pre-tax balance into the 401(k) before executing the backdoor conversion. Confirm rollover acceptance with the plan administrator directly.

The Nevada domicile: what zero state income tax means at captain pay

Nevada imposes no personal income tax. For a pilot domiciled in Las Vegas, state income tax on wages, profit sharing, and most retirement distributions is zero. This is structurally advantageous compared to nearly every other major airline base city in the country.⁴

Federal law (49 U.S.C. § 40116) prevents states from taxing nonresident airline crew income attributable to flights in other states. If you are genuinely domiciled in Nevada but fly routes through California or Arizona, those states cannot tax your non-home-state flight income. But the protection follows domicile — it doesn't create one. The checklist: Nevada driver's license, Nevada voter registration, primary residence in Nevada, no maintained apartment or home in a high-tax state, Nevada banking relationships, Nevada-registered vehicles. State revenue authorities audit airline pilots on domicile claims. See the Pilot Tax Planning guide for the full audit-risk checklist and what to document before a residency challenge.

The annual value of Nevada domicile depends on what you're comparing to:

vs. California: A captain earning $270,000 in California faces approximately $25,000–$27,000 in state income tax at combined rates of 9.3–10.3%. In Nevada: $0. Annual savings: $25,000+.⁴
vs. Minnesota (relevant post-Sun Country merger): Minnesota's top rate of 9.85% applies to MFJ income above $304,970 in 2026.⁴ A Sun Country pilot at $260,000 based at MSP pays approximately $20,000–$24,000 in Minnesota income tax. In Nevada: $0.
vs. Florida, Texas, Wyoming: No income tax states — no advantage over Las Vegas for those already in no-tax domiciles.

No DB pension: loss-of-license disability is the only financial backstop

Allegiant has never established a defined-benefit pension plan. There is no PBGC safety net, no fallback annuity, and no monthly benefit independent of 401(k) accumulation. If an Allegiant pilot loses their FAA medical certificate — voluntarily or involuntarily — the 401(k) balance, personal savings, and disability insurance coverage are the complete financial picture.

At airlines with DB pensions (Hawaiian Airlines, the frozen A Plan at American), a pilot with an early medical disqualification retains some pension benefit depending on vesting. At Allegiant, no such backstop exists. Every dollar of retirement security depends on what is in the 401(k) on the day employment ends.

This makes loss-of-license disability insurance non-optional — it is the structural substitute for a pension. Standard group long-term disability policies (60% of income, typically capped, with occupational-class language that may not pay for loss of FAA Class 1 medical) are insufficient on their own. An individual loss-of-license policy that pays when you cannot maintain the FAA medical certificate required for your certificate, regardless of ability to perform other work, is the appropriate coverage. See the Loss of Medical Disability Insurance guide for the policy language distinguishing real loss-of-license coverage from general LTD, and the Coverage Calculator to size the monthly benefit against your income and expenses.

The new-hire enrollment window — typically the first 60 days of employment — is the highest-value moment to apply: underwriting is most favorable, no medical examination is required, and premium rates are lowest. A pilot who misses this window must later qualify through full underwriting, facing higher premiums and potential coverage exclusions. This is the single most irreversible early-career financial mistake at any carrier with no DB pension.

The Sun Country merger: seniority, benefits, and what changes

Allegiant Travel Company completed its acquisition of Sun Country Airlines on May 13, 2026, for approximately $1.5 billion.⁵ The combined pilot group — approximately 1,400 Allegiant pilots (Teamsters Local 2118) and 700 Sun Country pilots (ALPA) — now flies under one corporate parent while temporarily operating under separate airline certificates and collective bargaining agreements.

The key open questions for financial planning purposes:

Seniority list integration. Allegiant and Sun Country fly separate seniority lists. A merged seniority agreement has not been finalized as of mid-2026. This determines who gets which routes, bases, and equipment over the integration period. The domicile implications alone — Nevada at zero state income tax versus Minnesota at 9.85% top rate — can translate to tens of thousands in annual state tax difference depending on where pilots land on the merged list and which bases are available to bid.
Benefits convergence. The two groups have materially different retirement structures: Allegiant's match-based 401(k) requiring pilot contributions versus Sun Country's 15% non-elective contribution requiring no employee deferral as of 2024.⁶ In joint collective bargaining, the combined pilot group typically pushes toward the better of the two structures — in this case, likely movement toward an NEC model and higher contribution rates for Allegiant pilots. A new contract could meaningfully increase Allegiant's effective employer contribution. Plan conservatively on the current match rate; model an improvement as upside if ratified.
Contract negotiation timeline. Both CBAs were in flux as of mid-2026. Allegiant's Teamsters contract was under active renegotiation after years of contentious talks. Sun Country's ALPA CBA became amendable December 2025. A single joint CBA for the merged entity would require resolving union jurisdiction questions and bargaining a combined agreement — a multi-year process. Until then, each group operates under its existing agreement.

The planning framework during integration: build your retirement projection on the current Allegiant match structure at your current base. If a better contract materializes or a favorable base transfer opens, you're ahead. If neither happens, your base-case plan still works. Early-career pilots deciding whether to stay at Allegiant or pursue a mainline upgrade should factor in that the post-integration benefits picture may improve substantially.

Career-stage priorities for Allegiant pilots

New hire: the match trigger and the disability window

The two first-year priorities are (1) set your 401(k) deferral to at least the 5% match trigger threshold on day one of eligibility, and (2) elect individual loss-of-license disability coverage during the new-hire enrollment window. Both have consequences that compound over a career: missing the match trigger for even a few months forfeits unrecoverable company contributions; missing the disability window forces full underwriting later. At regional FO income levels, the tax bracket is lower than it will ever be again — Roth 401(k) deferrals capture the bracket arbitrage that compounds into material Roth balances by captain upgrade. See the New Airline Hire Financial Checklist for the full first-year decision sequence.

Captain upgrade: full bucket optimization

The Allegiant captain upgrade shifts income into a range where backdoor Roth, HSA maximization, and taxable brokerage all become relevant in the same year. At Allegiant, the upgrade doesn't trigger a §415(c) squeeze as it would at mainline carriers — the bucket remains ample at every Allegiant captain income level. The priorities change: maximize the personal deferral (not just the match trigger threshold); update disability coverage limits to reflect captain income; begin the backdoor Roth annually, clearing any pre-tax rollover IRA balance into the 401(k) first; and fully establish the Nevada domicile checklist before income reaches peak captain levels where the state tax savings are largest. The Captain Upgrade Savings-Rate Calculator models three scenarios at your new income level.

Senior captain, ages 55–65: the compressed accumulation sprint

FAA mandatory retirement at age 65 applies to Allegiant captains exactly as it does at mainline carriers. The hard stop concentrates the final accumulation window. The SECURE 2.0 super catch-up (ages 60–63, $11,250 in additional Roth deferral outside the §415(c) limit) adds $45,000 in Roth accumulation across the four-year window — meaningful tax diversification for pilots without a pension income floor.³ Use the Pre-Retirement Checklist: Ages 60–65 for the year-by-year countdown: Medicare IEP timing, HSA 6-month lookback stop rule, Social Security bridge strategy, and the RMD window that opens at age 73 (born 1951–1959) or 75 (born 1960+) under SECURE 2.0 § 107.

Work with an advisor who understands Allegiant's match structure and the Sun Country integration

The match-based 401(k) mechanics, Nevada domicile setup and protection, no-pension disability planning, and the open seniority and benefits questions from the Sun Country integration are specific enough that a generalist advisor will be working through them for the first time on your dime. Match with a fee-only advisor who has worked with Allegiant pilots and other ULCC and low-cost-carrier clients through contract changes and integration periods.
