Britain's big summer getaway turned into chaos on 'Frantic Friday' today as an airport terminal was evacuated, a major motorway was blocked and trains were cancelled.
Many families were on the move after the schools broke up for summer, but there was disruption for those travelling to London Heathrow, Gatwick and Stansted airports.
An area of Heathrow Terminal 3 was cleared this morning while a fire alarm was investigated, which passengers said had caused huge waits for passport control.
The alert just after 11am led to the temporary evacuation being carried out by staff for safety reasons, which some travellers complained had led to two-hour queues.
Christina Warren, who had just arrived on a Virgin Atlantic flight, tweeted: 'Landed at Heathrow an hour early but there was a fire alarm so the line for passport control is literally backed up literally the entire terminal because of a fire alarm going off.'
