Check fares on popular carriers that connect the U.K. with Cuba. These include Cuba's national carrier, Cubana de Aviacion, and Virgin Atlantic, which often offers reasonably priced fares.
Look into indirect flights. Cheap flights are often available from Spanish cities like Barcelona and Madrid. English travelers may find a connecting flight in one of these cities to be more reasonably priced than a direct flight from one of London's airports.
Buy a round-trip ticket. All visitors from the U.K. must show a valid return ticket before they are allowed to enter Cuba.
Acquire a valid passport and Cuban visa. Travelers must have a passport that is more than six months away from its expiration date. A tourist visa can be procured at any Cuban embassy or consulate.
Recheck current visa and passport requirements. It is the responsibility of each traveler to make sure that their documents are in order before departure.
Keep up to date on the weather. Cuba is occasionally hit by tropical storms and hurricanes during the summer months. Though these storms are somewhat rare, they can be quite dangerous and cause significant damage to the country's infrastructure.
