British Airways have cancelled 72 flights today, affecting over 10,000 passengers, with further strikes set to continue over the busy Easter period.
The strikes are going ahead after security staff walked out.
Around 1,400 Unite members at Heathrow will strike from today until Easter Sunday on April 9 after last-ditch talks failed to resolve a pay dispute, with action now set to disrupt school holiday travel.
The union said talks broke down because Heathrow Airport Limited failed to substantially improve its pay offer.
Heathrow said that as at any busy time, it may take a little longer than usual to get through security during the strikes.
‘Passengers can help us ensure they get the best start to their journeys by checking their flight status with their airline before travelling to the airport, arriving at Heathrow no earlier than two hours before short haul flights and three hours before long haul flights and by being ready for security with their compliant liquids and electronics out of their hand luggage,’ it said in a statement.
Traffic is expected to be huge over the Easter Holidays with the AA estimating that millions of Brits will use their cars over the weekend.
Bank holiday traffic will peak on Saturday with around 15 million of Britain’s drivers planning to use their cars on April 8.
