Keeping the GB's A320s and A321s in the fleet might result extremely hasardous for easyJet in the near future.
Those aircraft do have a higher operating cost (more fuel, more cabine crew, etc) and compared to an A319 it will obviously be more difficult to reach a reasonable passenger load outside of the summer season.
The good point of those aircraft is that they can fly onto longer routes such as MAN -> Canaries/Egypt,etc.. but then it's not really the easyJet's policy to fly that far, because it seems to be more lucrative to make 2 shorter flights with an A319 instead of a longer one with an A320/321 for the same amount of time.
Also, the A319/A320/A321 conversion course for all Airbus cabine crew and flightdeck crew will cost easyJet a lot (moneywise and timewise).
Lastly, I am surprised that the LGW/Corsica routes previously operated by GB in summer are not anymore on the map.
