easyJet - Must admit that I was expecting a couple more based aircraft, however as has been said there is nothing to stop the introduction of services from overseas bases such as GVA/MAD/MXP + ??
Ryanair - Yes, BRE is a possibility plus another continental based destination. If you look at the wording of the MEN announcement you will see that they talk of FR doubling their operation. Remind me if I'm wrong, but that only relates to an additional 5 flights per day - which I would not classify as being a massive expansion.
As Suzeman says, each airline will be aware of the slots being held by their competitors after the slot conference and so we will have to see what is announced tomorrow.
