British Airways is cancelling more flights in July, with up to 105,000 holidaymakers affected, according to reports.
The airline has reportedly told airport slot authorities that it will axe more than 76,000 seats from Heathrow and 29,400 from Gatwick.
The Telegraph reports routes including Malaga, Ibiza, Parma, Faro and Athens will be hit.
A BA spokesperson said: “We took pre-emptive action earlier this year to reduce our summer schedule to provide customers with as much notice as possible about any changes to their travel plans.
“As the entire aviation industry continues to face into the most challenging period in its history, regrettably it has become necessary to make some further reductions. We’re in touch with customers to apologise and offer to rebook them or issue a full refund.”
