No, you do not tip flight attendants for drinks or any other service on a commercial flight in 2026. In the aviation industry, flight attendants are considered safety professionals rather than "waitstaff," and most airline contracts actually prohibit crew members from accepting cash tips. Attempting to tip can be awkward and is often viewed as an insult to their professional standing. If you want to show appreciation for exceptional service, the most valuable thing you can do is write a commendation letter or mention the attendant's name in the post-flight survey sent to your email; these go directly into their personnel file and can lead to promotions or bonuses. Alternatively, small "gestures" are becoming popular in 2026—many frequent flyers bring a small bag of sealed chocolates or a $5–$10 Starbucks gift card to give to the crew at the start of the flight as a "thank you" for their hard work.
