However, through May 1, cash was your only option for paying for in-flight purchases on American Eagle flights. Thankfully, that’s now a problem of the past.Effective May 1, all American Eagle operators will accept “all major debit and credit cards,” making American Airlines “cashless across all flights.” According to American Airlines, this is part of a larger effort to “align our mainline and regional customer experience so customers have a seamless experience and similar products on both American and American Eagle.“While this isn’t a major development, it’s a good chance to make sure you’re using the right card for purchases on board American Airlines flights. The best cards to use are the ones offering 25% off the in-flight purchase plus 2x AAdvantage miles on eligible American Airlines purchases:Citi / AAdvantage Executive World Elite MastercardCiti / AAdvantage Platinum Select World Elite MastercardCitiBusiness / AAdvantage Platinum Select World MastercardBarclaycard AAdvantage Aviator Red World Elite MastercardThe information for the Citi AAdvantage Platinum and CitiBusiness AAdvantage Platinum card has been collected independently by The Points Guy.
