NCL - Oslo Torp and Oporto-Beavais are just 2 routes that I can think of that FR operate with a non-based a/c.
On the AGP front, that you be a good move for FR, but surely they can't compete with EZY and ZB on the UK front can they? Almost every airport in the UK has an AGP connection from usually more than one carrier with multi-daily flights. But hey. whoever stopped FR?!
