Unless you live on one of the surrounding islands, you will most likely have to take two flights to get to Nevis. The first one brings you to an island that is larger than Nevis, with a much larger airport, like Puerto Rico. At those airports, you get on a smaller plane that holds about twenty people. They fly over to Nevis's tiny airport. Nevis at one point had their own airline, but had to end that because of the expense. Some people may be able to find direct flights to St. Kitts and then just get a ferry over to Nevis.
