Aviation consultant John Strickland of JLS Consulting said Europe’s airlines had recorded only 12% of revenue and 15% of May to September bookings this year compared with those made by 20 March 2019.
“Part of the summer at least, is going to be a write-off,” he said.
Speaking at the World Aviation Festival Virtual, Strickland said: “It is amazing to think we were talking about this a year ago and hoping it was only going to last a matter of months.”
The UK’s traffic light system, he said, was “stuck on red” because no details had yet emerged of which destinations would fall into which category.
