I don't think they are going to have a short haul base anytime soon as any fees they pay to SNN pay for FR to fly for free. We shall see.
No doubt EI are going back on SNN-LHR paying a lot less fees.
SNN offered a sharp reduction when EI pulled out, so now I'm sure they're taking them up on the offer.
Probably getting a very similar deal as Air France do on CDG.
