HH6702 Excel have as yet not decided on what kind of programme they will offer for S08, if any. Most of the flight released so far are operated by third party carrier, with only a single few flights planned as XLA. SSH is one of the flights not planned to operate next summer, so it seems there will be vast consolidation, reduction in frequency on the charter front too.
In reference to Jet2, I think that there could be another ski route planned, LYS, SZG or something similar. Their CMF did extremely well last winter and it makes good use of aircraft down time and the routes to such destinations tie in perfectly with the quiet time of year in the 'sun' places with the busy time in the Alps.
Any news on the rumoured German/Italian loco operator?
