when is the best time to travel to Europe from the Caribbean and which airline would offer the cheapest fare?

If you are a student or even under 26 try StudentUniverse.com I made it to Europe from NYC for less than half the actual airline price.

XL.com can probably get you to London and back in March for about $750.

You definitely want to avoid travel in the high seasons for Europe i.e the summer time- so before May this year is ideal or between September and December- Christmas is rough for discount tickets.

Good luck, safe travels.

they are many but Air France and Lufthansa !
