Flyr is a low-cost Norwegian airline operating to a range of European destinations from Oslo. If you don’t know the name, you may know the name of founder Erik G. Braathen who owned the now-defunct carrier Braathens.
The carrier launched in late 2021 and has a fleet of 12 Boeing 737 aircraft.
Flyr is planning to launch flights from Gatwick to Oslo for the Summer 2023 season, starting in late March. These will compete with Norse Atlantic, albeit Norse Atlantic has a very attractive Premium cabin which I reviewed here.
There will be six flights per week (no Saturday services) with generally early evening departures from London, arriving late into Oslo.
If you are planning a visit to Oslo I’d suggest you fly out on Norse Atlantic (noon departure from London) and back on Flyr (4pm-5pm departure from Oslo) if you want to maximise your trip.
Note that Flyr has financial issues at the moment which you may want to consider before booking. You should definitely use a credit card for extra protection if you do book.
