Why use the slots at all? Virtually every Jet2 adventure onto domestic routes has been a disaster! MAN-EDI, MAN-LGW, now NCL-LGW, wasn't there an EDI-BOH at one stage withdrawn before it even started.... only LBA and BLK to BFS seem to hang in there. It rather looks as though the Jet2 model works well on sunny places but UK domestics are not for them.
