New routes from Birmingham and Liverpool are being introduced by Ryanair.
The no-frills carrier is to serve Poznan in Poland from Birmingham twice a week from July 3.
Kaunas in Lithuania will be operated from Liverpool twice a week from July 4.
Fares on both routes lead in at £24.99 for travel until the end of October when booked by midnight on March 21.
Commercial director Jason McGuinness, said: “Mindful that Covid restrictions change regularly, customers can now book flights for a well-deserved break knowing that if they need to postpone or change their travel dates, they can do so up to two times with a zero-change fee until the end of October 2021.”
