Bases, pay, training, hiring windows and the interview process — from dated sources.
Last updated August 2026 — dated facts carry their own as-of dates below.
Mesa Airlines is, as of August 2026, a wholly owned operating subsidiary of Republic Airways Holdings — the merger closed November 25, 2025 — still flying on its own FAA certificate: an all-E175 operation (60 United-owned aircraft), 100% United Express, with legacy headquarters in Phoenix. Note the change from older material: new-hire training has moved to Indianapolis under Republic — it is no longer run in Phoenix. Phoenix remains HQ, not a training site. The key structural answer for a 2026 applicant: you are hired by Mesa Airlines (own certificate, own AFA-represented seniority group), not by Republic — but you join a company mid-absorption, covered by the ratified joint Mesa/Republic flight attendant contract. How long Mesa-branded FA hiring continues before folding into Republic's recruiting funnel is not documented — treat it as a moving part.
The honest 2026 story is transition, and candidates who tell it accurately stand out: Mesa is a survivor airline (dropped by American in 2023, financial distress through 2025, rescued by the Republic merger) now stabilizing inside a larger, healthier parent with new long-term United flying. Neither dooming ("Mesa is dying") nor denial ("nothing changed") survives contact with an interviewer who lives it.
The labor arc is the good news, and it is unusually concrete: (1) October 13, 2025 — Mesa's AFA members ratified (94%) a two-year contract equalizing Mesa pay with Republic before merger talks. (2) December 2025 → January 22, 2026 — Mesa (AFA) and Republic (IBT) FAs ratified a joint contract (JCBA) by 91%, covering nearly 3,000 combined FAs. The JCBA's headline: boarding pay that matches the standard mainline formula (50% of the hourly rate during boarding) — making Mesa/Republic one of the very few regional FA groups with mainline-style boarding pay, part of a package AFA characterizes as raising compensation up to 16% on average (union-sourced figure). The JCBA is expressly a midterm bridge: full joint Section 6 negotiations begin January 2027, so a new hire works under it with another negotiation round already scheduled.
One requirement is a genuine differentiator: verbatim from Mesa's requirements page — "At least 20 years old." Mesa is the only carrier in our research set with a sub-21 age floor (Delta, Endeavor, Piedmont, Horizon, and SkyWest are all 21+). Other requirements (official pages, checked August 2026): high-school diploma or GED; college credits or two years of customer service experience preferred (not required); current valid U.S. or foreign passport with unrestricted travel to/from Canada, Mexico, the Bahamas, and Cuba (unusual — check your own visa situation); FBI fingerprinting; DOT/FAA drug screen with "medical marijuana prohibited" verbatim; English fluency. No height range or reach number is published — the standard is functional (overhead bins, doors, jumpseat fit without modification, overwing exits, aisle, and endurance to "work up to 16 hours per day"). No swim test found.
Three FA bases as of August 2026 (official page): Houston (IAH), Washington-Dulles (IAD), and Louisville (SDF). A Sterling, VA posting you may see on Glassdoor is the IAD-area listing, not a fourth base — don't count it separately. Phoenix is HQ only — not a line-flying base and, as of the current wave, not the training location either — and Denver is not a Mesa base; both appear in stale content. Per the official page, "bases are assigned during the first few weeks of training and are awarded based on operational need and seniority" — expect the junior base and reserve first. The base map could shift as Republic rationalizes the combined network; re-verify monthly.
Union/entity map for a 2026 new hire, stated precisely: hired by Mesa → represented by AFA-CWA; Republic's FAs are represented by IBT Teamsters Local 135; the January 2026 JCBA covers both groups economically, but the seniority lists and union certifications remain separate until certificate consolidation (guided late 2027–early 2028) triggers a single-carrier determination and a representation vote. Which union ultimately represents the combined ~3,000 FAs is unresolved — expect a representation vote and seniority-list integration during your first years, and don't let anyone tell you the winner is known.
Mesa FAs are paid per flight hour — boarding is now partially compensated (below), but ground delays and standby are not paid at the full hourly rate. First-year math must use realistic flight-hour months (the regional norm is a ~75–76-hour guarantee; Mesa's own guarantee figure was not found), never 160 duty hours.
Mesa Airlines's requirements page states a minimum age of 20, a high school diploma or GED, and functional physical requirements rather than a published height or reach threshold.
