Age 20 and age 21 are the main published thresholds here
Southwest and Frontier
Their reviewed evergreen pages state a minimum of 20. An active opening can still add other qualifications and timing details.
United, Delta, Alaska, and SkyWest
The reviewed sources for these airlines state a minimum age of 21.
Sun Country
The reviewed threshold is age 20 by the end of training, so an applicant who is 19 needs the actual training timeline before reaching a conclusion.
What to check before an opening goes live
- Calculate your age on the date named by the current listing—not only today’s date.
- Confirm whether the airline says “at application,” “before training,” or another date.
- Do not assume an unspecified upper-age limit; use only current published criteria.
- Check the other threshold requirements, especially passport timing, work authorization, education, and customer-service experience.
Meeting the age threshold only removes one potential blocker. It does not indicate that an airline is hiring or predict an application outcome.
American Airlines:
The reviewed evergreen careers page did not expose a stable full minimum-qualification list. The table therefore says Check active listing instead of guessing from older or third-party material.
