If you’re looking for American Airlines senior discounts, the key is knowing where to check and what to expect, because they’re not always advertised. American Airlines doesn’t offer a guaranteed senior fare on every route, so the best approach is to compare regular online prices first, then call reservations directly to ask if any age-based or unpublished fares are available for your specific route and travel dates. Senior discounts, when they exist, are usually limited to select domestic flights, off-peak travel, and economy class, and eligibility typically starts at age 65.
