About 100 people have been left stranded in Milan after a flight to Manchester left without them.
They were due to depart on an Easyjet flight on Sunday but faced queues of up to three hours at Milan's Linate airport because of new border control checks.
Marooned passengers told the BBC people had been vomiting and passing out in the heat and now did not know how they would get home.
Easyjet said it was trying to support passengers but that the situation was "outside of our control".
One passenger, Kiera, 17, from Oldham, told the BBC she and her boyfriend faced a 20-hour wait in the airport until they could get another flight tomorrow.
