A groom called Thomas Cook says he is "extremely relieved" that his dream wedding in Greece went ahead despite the collapse of the travel firm with the same name.
A total of 100,000 bookings made by direct debit would be refunded within the next 14 days.
The CAA said this is three times larger than any previous refund programme, and on October 7 it will be launching an online refund system to cope with demand.
The CAA was due to launch a dedicated website form today to handle the 360,000 Thomas Cook claims it expects to be made under the Air Travel Organisers Licence (Atol) scheme.
"We have had to pay for everything again that was booked through Thomas Cook but a local wedding company has helped us out".
The costs are still being worked out by Government officials, but initial estimates suggest the repatriation will be double the £50 million it cost when Monarch Airlines collapsed in 2017.
CAA said more than two-thirds of the total number of customers have been repatriated.
"The goal is to ensure continued operations for the French subsidiary and rapidly find a takeover solution", Thomas Cook France said.
