EasyJet and Jet2.com have bought all of the take-off and landing slots owned by collapsed travel firm Thomas Cook in UK airports.
The slots at London Gatwick and Bristol were bought by EasyJet for £36m, the government's liquidation service said.
Jet2.com has bought slots at Manchester, Birmingham and Stansted airports for an undisclosed amount.
Thomas Cook's UK business and airline entered insolvency in September, when a court appointed an official receiver.
EasyJet bought 12 summer take-off and landing slots, called pairs, at Gatwick and eight winter slot pairs.
It also bought six summer slot pairs and one winter slot pair at Bristol.
The slots will expand the airline's presence at each airport.
Gatwick says it is working with EasyJet to try out new ways to board passengers at the London airport.
These include boarding people in window seats first, starting at the back, followed by middle then aisle seats.
How wonderful it is that nobody need wait a single moment before starting to improve the world.
