The boss of Heathrow Airport has apologised to the over 200,000 passengers whose journeys were disrupted by its closure last month following a fire.
Thomas Woldbye offered his “deepest regrets” adding that the “situation was unprecedented”.
Speaking to MPs, he said he recognised “the considerable inconvenience and concern it caused”.
The airport was shut down for more than a day in March after a fire at a nearby electrical substation.
