Delta Air Lines, the most profitable U.S. carrier, is raising pay for nonunion employees as it gets ready for another attempt by a union to represent its flight attendants.

CEO Ed Bastian told Delta employees Monday that the airline will boost pay for flight attendants and ground workers by 5%, raise the minimum wage for U.S. workers to $19 per hour, and set aside money for merit raises.

Delta said the increases affect more than 80,000 employees.
