British Airways has announced it will cut a further 10,300 short-haul flights until the end of October.
The latest news for the airline is another major blow for Brits hoping to get abroad this summer.
It comes a day after the UK's flag carrier said that it would give back flight slots this summer, cancelling hundreds of flights.
The cuts will run from the beginning of August until the end of October and are all short-haul, with long-haul unaffected in this round of cancellations, BA has said.
In total 13% of BA flights will have been cancelled this summer.
BA has been ravaged by cancellations and delays this summer as it struggles to get flights in the air and services running on time amid serious staff shortages.
A spokesperson for the airline said: "The whole aviation industry continues to face into significant challenges and we're completely focussed on building resilience into our operation to give customers the certainty they deserve.
"The Government recently decided to give the whole industry slot alleviation to minimise potential disruption this summer. While taking further action is not where we wanted to be, it's the right thing to do for our customers and our colleagues.
"This new flexibility means that we can further reduce our schedule and consolidate some of our quieter services so that we can protect as many of our holiday flights as possible.
"While most of our flights are unaffected and the majority of customers will get away as planned, we don't underestimate the impact this will have and we're doing everything we can to get their travel plans back on track.
"We're in touch to apologise and offer rebooking options for new flights with us or another airline as soon as possible or issue a full refund.
"In the Spring the airline reduced its schedule by 10% until October, in a bid to get those remaining flights running smoothly."
The latest announcement adds to that number, and is likely to impact hundreds of thousands, if not more than a million, passengers.
There also appears to be dissatisfaction within the BA ranks.
The airline is believed to be talking to union officials to avert possible strikes that would bring more air misery.
Airline chiefs are understood to be meeting the Unite union over a pay row involving about 500 check-in staff at Heathrow and issues raised by other BA workers.
Last month a Unite ballot of its 16,000 BA staff received 97% backing for potential industrial action.
A source said: “It will be a pretty important meeting. If they want to buy themselves some time they can do something on pay but there are a lot of other issues to resolve.”
Those issues cover everything from rosters to meal allowances.
Today a BA pilot told The Mirror that disquiet among pilots was growing quickly.
"I get a sense some disruption is inevitable at some point, it's a question of when I think," they said.
"Once one group of pilots strike and take a stand against what's been going on, it'll spread quickly across the industry."
The pilot said the fear of having a black mark next to their name was what was stopping workers from launching industrial action.
