Last time I checked it was 2x A320 and 2x A321 from LGW and 1x A320 from DSA. Everything else operated by TUI. Newcastle is 4x 738/MAX. The 4 ACMI at LGW is essentially a like for like replacement of Norwegian pre-covid.
By all accounts bottom feeders Avion Express and Smartlynx haven’t got anywhere close to the number of pilots they need for summer, so I’m sure it’ll be a fun summer season for all who’ve decided to go down the path of cheap foreign contractors. TUI, Jet2, easyJet and BA are all signed up.
