INDIANAPOLIS (WTHR) — Most people tip a bartender, the waitress, the delivery driver, but what about a flight attendant?

U.S. based budget airline Frontier Airlines has started asking passengers to tip their cabin crew, specifically flight attendants, as the attendants are bringing around refreshments.

The new suggestion was noticed by blogger JT Genter who was given a mobile tablet after ordering a drink on his flight.

The tablet, which is how a customer would pay for the drink, had buttons for gratuity, too — 15%, 20%, 25% and custom gratuity.

"Gratuities are appreciated," the screen's message read.

Asking for a tip isn't usual protocol for most airlines.

A Frontier spokesperson told BusinessInsider that tips are shared among all members of the flight attendant crew.
