Rory Boland, Which? Travel Editor, said:
“Passengers affected by the disruption at Heathrow should have the right to food, refreshments and overnight accommodation for long delays. If a flight is cancelled or delayed by more than five hours and you decide not to travel, you should also be offered an alternative flight or a full refund.
“Those who do miss flights because gate information wasn’t available should be offered help by their airline to get to their destination on the next flight.”
