More than 80,000 Monarch holidaymakers have been repatriated to the UK as part of an operation expected to cost £60m.

The Civil Aviation Authority put on 567 flights which brought back 83,875 passengers to the UK after the travel company went into administration.

The last of the flights - a service from Tel Aviv, in Israel, with 122 passengers - landed at Luton Airport at just after 3.30am yesterday.

The CAA said it is contacting all 1,000 Atol protected passengers still abroad in order to arrange alternative flights to get them home when their trip has ended.

A spokesman for the regulator said the operation is expected to cost in the region of £60m.

CAA chief executive Andrew Haines said: “This has been a phenomenal challenge and one that has required the co-operation and support of many businesses, government departments and individuals.

“It was a very sad day when Monarch went into administration and our thoughts remain with all the Monarch employees who have lost their jobs.”

He said 98 per cent of passengers arrived home on the day they were scheduled to return.

Administrators KPMG said 1,858 of 2,100 people employed across Monarch’s airline and tour group had been made redundant. Nearly 100 of those were employed by Monarch Travel Group, while 1,760 were employees of Monarch Airlines.

The remaining employees will help with the administration process, and assist the CAA in bringing holidaymakers abroad back to the UK, KPMG said.

Atol was the UK’s holiday financial protection scheme and costs £2.50 per customer. By law every UK-based travel company that sells air holidays has to have a licence.

The largest Atol company to stop trading before Monarch was XL Leisure Group in 2008, which had 43,000 people abroad at the time.
