Additional flights CL Final
Currently looks as if particularly LGW will get substantial additional traffic from the CL final 25th May, but also additional flights to STN.
All airlines appear to have (where possible) upgraded their equipment on all London routes. Cityjet sees fully booked planes on Sunday LCY-FMO/NUE for first time.
In addition (and this is only what's bookable to the public, and available so far. Tickets get allocated this weekend which should result in another booking frenzy):
LH: Will fly multiple MUC-LGW-MUC
Vueling (!): Whilst Spain won't play, currently 2 MUC-LGW-MUC and 2 DTM-MUC-DTM bookable via their website
Germanwings: Extra DTM-STN-DTM
AB: Additionals on DUS-STN-DUS
FR: Multiple additional flights from NUE, FMM, NRN to STN
Easyjet: Additional services
As I say, I suspect more to follow, and there must be plenty of charters arranged away from the public booking channels. The aprons should see a lot of parked aircraft Saturday->Sunday!
