Delta Air Lines, which is facing another attempt to unionize its flight attendants, will begin paying cabin crews during boarding, a first for a major US airline.
Across the airline industry in the United States, hourly pay for flight attendants starts when all the passengers are seated and the plane's doors close.
Delta said the change will start on June 2 on all flights.
In a memo to flight attendants, Delta's senior vice president of in-flight service, Kristen Manion Taylor, said the new pay "further recognizes how important your role is on board to ensuring a welcoming, safe and on-time start to each flight."
The rate of pay during boarding will be 50 per cent of regular wages.
