The boss of US low-fare carrier JetBlue has said it is necessary to over-hire staff because of the rate at which people are still leaving the industry.
Robin Hayes was speaking as thousands of travellers have been hit by recent disruption - caused largely by staff shortages that have blighted the re-start of air travel after the pandemic.
Airlines have cut summer schedules and made last-minute cancellations.
"I now need to over-hire just to keep the number I need," he told the BBC.
"With Covid, we lost a lot of experienced people," Mr Hayes added.
