From Cancun to Cuba?

Hi there! I hope I can get some tips from those who have been in at least the similar situation as Im in now. Actually, Im traveling from London to Havana but I must drop by to Cancun before Cuba. So, Im getting a plane to Cancun but what do you suggest me from Cancun to Cuba? What do you think about those low cost companies? I must add that Im trying to save some money.

I would never trust low cost companies, and would travel only with high class airlines. Im so afraid of traveling by plane that if its a must then it has to be a famous company, with good rates. The link between Cancun and Havana is quite well and you could choose among many airlines, it depends, of course, on money youre about to spend on the plane ticket and the exact time youre supposed to be in Havana. I know that sea can be rough but I prefer water to air, I mean you can swim but you cant fly, so Id always pick a ferry or a boat. And that is certainly cheaper than airplane. At least I think so. But it takes much more time. Surf for a while and youll find information.
