I am going to visit a friend in the Cayman Islands for a few days at the end of the year but flights are much cheaper if I fool around with the dates and airports.

I'd like to fly in and out of Belize and then head over to George Town. Is there a cheap airline that has direct service between the two? Can I take a boat? I don't mind if that takes a while.

Also, I am American and am dying to go to Cuba. I know I can grab a flight to Havana from George Town but I am not sure which airline to take/if there is a boat. I currently live in Canada so I am not worried about the financial situation of being in Cuba.

Thanks!
