After 21 years as a service agent at Air France, Karim Djeffal left his job during the COVID-19 pandemic to start his own job-coaching consultancy.

"If this doesn't work out, I won't be going back to the aviation sector," says the 41-year-old bluntly. "Some shifts started at 4 a.m. and others ended at midnight. It could be exhausting."

Djeffal offers a taste of what airports and airlines across Europe are up against as they race to hire thousands to cope with resurgent demand, dubbed "revenge travel" as people seek to make up for vacations lost during the pandemic.
