I would say that apart from a few city break routes the overwhelming majority of Jet2's business is bucket and spade to the Med., and the flight operated mainly for the benefit of it's group company Jet2 Holidays - which is why some aircraft are liveried as such.
it would be interesting to compare the split between package and independent travelers booking on Jet2 bucket and spade routes, and compare the ratios with those of TCX / TOM. I reckon there wouldn't be a lot of difference.
Difference between Jet2 and the others is that Jet2 spawned the tour operator, whereas with the other two, tour operators spawned the airline.
Please don't kid yourselves that Jet2 won't change flight timings between now and Summer 2016. Slot allocations at the more congested airports haven't even started yet for S2016, and you can be sure that if a destination isn't selling as expected then consolidations and cancellations will take place - whether they are called that is another matter.
