ok jet2 wouldnt make a lot of money with a few days a week flying out of southend coz thay would have to put crew up in hotels and the fuel flying the aircraft to southed and it would be a wast of money basing staff there
How do you know that? Why would they base crew there if they are already 'putting them up in hotels'? How do other operators get away with operating schedules like that, when you say that it would be too expensive for Jet2?
If Jet2 would 'make more money' from flying 'LBA-PRG-SEN-PRG-LBA' then why dont they go down that route more often?
