We spoke to American Airlines, Delta, and United, and each airline generally discourages flight attendants from accepting tips. That's pretty much the rule across the board — except for Frontier Airlines. In 2019, the airline introduced tipping options for onboard purchases of food and drink.

While you can offer a tip to an airline steward (flight attendant), it is generally discouraged and often against airline policy. Most major carriers—including Delta, United, and British Airways—view their cabin crew as "safety professionals" rather than service-industry workers like waiters or porters. Accepting tips can create a conflict of interest or lead to perceptions of preferential treatment during an emergency. Some airlines, like Frontier, actually have a formal "tipping prompt" on their payment tablets, but this is the exception. If you attempt to tip on a legacy carrier, the attendant may politely decline or be required to turn the money over to the airline or a charity. A much more valuable way to show appreciation in 2026 is to provide a "Cast Compliment" or "Job Well Done" certificate through the airline’s app or via a formal email. This goes on their permanent employment record and can lead to bonuses or promotions. Small gifts like sealed boxes of chocolates or Starbucks gift cards are generally accepted and highly appreciated, as they are seen as gestures of kindness rather than "payment" for service.
