EasyJet has added 140,000 extra seats on Belfast flights.
The additional seats previously served by Flybe, will help serve the demand for domestic travel.
The airline operates more seats on domestic flights than any other UK carrier.
The additional seats include Belfast International to London Luton, Glasgow and Manchester.
The airline also announced two new year-round domestic routes from Belfast City to London Luton and Manchester.
This means the airline now operates six routes from Belfast City including Bristol, Glasgow, Liverpool, and London Gatwick.
EasyJet relaunched operations from Belfast City for the first time in over 10 years in 2021.
Belfast fights to London Luton and Manchester will launch on 26 June 2023.
EasyJet will also be basing an aircraft in Belfast City overnight from June.
This enables a new 06.00 am departure to London Gatwick.
The airline will now offer up to four daily flights between Belfast City and London from next summer.
