American Airlines expects the travel boom to last beyond this summer.
The carrier has told the remaining 3,300 flight attendants on voluntary leave to come back by November or December and that it will and start recruiting new cabin crew members, according to a note to staff sent Thursday, which was reviewed by CNBC.
“Increasing customer demand and new routes starting later this year mean we need more flight attendants to operate the airline,” said the note.
