I am heading to Cancun, Mexico in three weeks. I also thought of going to Brazil, but it is just too far and expensive. Even Cancun was questionable because of the lack of money. Luckily, some friends also decided to go with me, and with them my financial status went up at least one level! So, what would be the cheapest airfare to Cancun?
You have chosen the right place for a summer vacation. Even though the September is very near, the weather is still warm and beautiful for water sports (which I adore) and all sorts of other activities. As for cheaper flights, perhaps you could try with lastminute.com, I know for certain that they fly to Cancun and that the prices are more than reasonable.
