I tried to book you on Ryanair but there was no availability on their website either - looked like all their Paris flights are already fully booked.
As far as I am aware none of Ryanair's flights for summer 2010 are on sale yet
I'm trying to book some tickets for a trip next May but it will only allow me to book as far ahead as Mar 29th. It seems to be only Paris as I can book flights to almost any other city for those dates (and later).
I can get the flights I want at a fairly reasonable rate on AF but theres a party of eight of us and I'd like to try and give the business to EI.....
Quite a number of EI's routes are not on sale yet for Summer 2010. I'd imagine the full schedule will be gradually released over the next month or two. CDG is a slot restricted airport so perhaps EI haven't yet finalised their slots with the airport authorities.
