The proposed strikes involving Heathrow airport staff have been called off for today, as bosses fight to avert a further strike tomorrow.
Around 2,500 planned to walk out for two days over pay conditions, threatening to throw the airport into chaos during its busiest period.
However the strike has been cancelled for today, with airlines reinstating flights departing from the airport.
British Airways, Air Canada, Aer Lingus and Etihad Airways have all stated that they will be reinstating flights and plan to operate a full schedule.
Virgin Atlantic had previously diverted its flights to London Gatwick and will not revert them back to Heathrow.
Passengers are still being advised to check with their airline before flying today and tomorrow and for those who are travelling on confirmed flights, expect longer than normal waits at security and baggage desks.
