We are trying to plan ahead and will be visiting Barcelona in May of 2014. Unfortunately airlines such as Vueling and Easyjet don't allow to book that far ahead or even to see what the airfares would be. Right now we plan on flying into Paris spend 5 days there, then onto Barcelona for 5 days and then Athens for 5 days.
If anyone can help with an approximation of what airfares might be lowest to (worst case) highest that would be appreciated. Paris to Barcelona
Barcelona to Athens
For the Paris to Barcelona journey, should we even consider going by train?
Lastly, does this seem to ambitious a plan?
Thanks for any help.
