The organisation completed 58 flights in its second day of operation on Tuesday, returning 11,478 people to the UK. It comes after Monarch Airlines collapsed in the early hours of Monday.

With 12 days remaining and approximately 87,431 passengers still to bring back to the UK, the CAA said it is working around the clock, in conjunction with the government, to deliver the replacement flying programme.

Today the CAA plans to operate 54 flights, bringing more than 11,091 people back to the UK.

Richard Moriarty, group director of the consumers and markets group of the CAA, said: “Our operation to bring people home continues to progress well, with a total of 23,321 people already back in the UK, including the first planeload of passengers from Greece. We are planning 54 flights on 4 October, for an additional 11,091 people.

“Fight details for people due to travel back to the UK on 5 October are already published on monarch.caa.co.uk, our dedicated website which has already seen over one million visitors over the past couple of days.

“We have everyone’s original flight details and our plan is to publish new flight details as soon as possible, normally 24 hours in advance of travel.”

On Tuesday the CAA published new information on claiming a refund for Atol protected customers whose trips were cancelled.

Customers who booked directly with Monarch Holidays using a credit card, are advised to contact their credit card issuer to make a claim for a refund.

All other Monarch Holidays and all First Aviation Limited customers will be sent a claim form by October 11, either directly by the CAA or via their travel agent.
