Heathrow Airport is holding last minute talks with unions to avoid strike action that could affect thousand of passengers tomorrow and Tuesday.
The UK's busiest airport has already cancelled 177 flights as a precaution.
The airport worker's union, Unite, and airport management began talks again at 10 this morning.
Industrial action is planned for 5th & 6th August. We want you to be as prepared as possible ahead of your flight, as some passenger journeys will be affected.

Here Aer Lingus says it's hoping to operate a full schedule but passengers booked to fly to or from Heathrow on Monday and Tuesday can re-book free of charge.
Around 4,000 Unite members voted on the airport's revised pay deal on Friday, with 88% opting to strike.
Unite regional co-ordinating officer Wayne King said: "This latest vote for strike action points to growing anger among the airport's workers in a whole range of vital jobs which are essential to the smooth and safe running of Heathrow.
"Airport bosses need to heed this latest strike vote and the overwhelming rejection by our members of the revised pay offer which offers little over and above the original offer of £3.75 extra a day for many workers."
Meanwhile, talks aimed at averting a separate strike by British Airways pilots are to continue next week.
Leaders of the British Airline Pilots Association (Balpa) met the company last week to try to resolve the dispute over pay.
The union would have to give two weeks' notice of any industrial action
