UK airlines and airports have cancelled thousands of flights in the past few months amid continued recruitment difficulties following coronavirus redundancies.
On Tuesday, Heathrow Airport introduced a 100,000-a-day passenger departure limit lasting until 11 September.
But this kind of disruption isn’t just happening in the UK.
Strikes and staff shortages are also forcing European airlines to cancel thousands of flights, causing hours-long queues at major airports.
According to AirJournal, there have already been 16,000 cancellations in August that were prevantable.
Here are some of those facing disruption this summer that UK tourists should be aware of…
