What we haven't thought is that the scheduled routes may have an Airbus flight deck crew based at Leeds. The charter routes may be served by a 757, which makes the longer routes more feasible operationally, but be crewed by Manchester 757 flight deck. The cabin crew could operate both without any problems. The 'charter' aircraft is not that heavily utilised compared to the scheduled routes so I'm sure it wouldn't be THAT expensive to send over a couple of flight deck each day in a taxi from MAN. Operationally an Monarch A320 would struggle to SSH as they are not the most powerful aircraft, similarly the A321 would struggle.
Either way it will be very interesting and almost exciting to see how it all develops. It does make financial sense really to operate Thomas Cook/Thomson's flights with Monarch as there is going to be a crew base and handling agreement already set up with the scheduled routes. No doubt a much lower cost to the tour operators that putting their own aircraft in as there are various economies of scale.
I will be interested to see how Monarch fair with performance with the A320 from Leeds, the majority of their A320's have the lesser powerful engine option. I don't know if anyone notices that Thomas Cook generally operate the same aircraft out of Leeds, either G-OMYA, G-SUEW, G-DHRJ or G-KKAZ? These are the more powerful A320's. Much like Jet2's 737-300's, the lesser powerful aircraft are subject to much more performance issues. Monarch's A320 fleet is fairly old compared to Thomas Cook's and generally have the CFM56-5A engines which are first generation A320 engines, which are less powerful than the CFM56-5B engines Thomas Cook have on their newer A320's that circulate through Leeds. One of our neighbours used to be a 757 pilot for MyTravel at Leeds and he convered to the A320 when we had Skyservice operating out of Leeds and he said as much as MYT's 757's needed serious work doing to them, they were a pleasure to fly out of Leeds compared to the Airbus which needed constant non standard departures and special performance. He said A320 family was designed to operate from hub airport to hub airport with perfect long runways and not from any payload restricted or extreme airfields. Be interesting to see how it all goes next year. Leeds has never had a serious Airbus operator on longer routes (well apart from the dodgey Turkish charters and odd TCX) so I'd love to see how it all works.
