Book your passage. Due to the interest in trans-Atlantic cruises, book your tickets well in advance, as they may sell out quickly. Numerous cruise lines offer trans-Atlantic passage; however, Cunard's Queen Mary II maintains a regular schedule of trips once per month from the U.K.
Gather your documents. Citizens of the U.K. and Ireland will need a valid passport and a return ticket dated no more than six months after their arrival in the U.S. No visas are needed, as the U.S., Ireland and the U.K. have a visa waiver agreement. U.S. citizens only need their passports. Some cruise companies offer airfare as part of a package deal for trans-Atlantic crossings.
Travel to London or Southampton and board the ship. Most trans-Atlantic cruises depart from these two locations. In some cases the cruise line may pick you and your luggage up from a hotel, train station or airport. In order to make embarking run smoothly, many cruise ships offer assigned, staggered boarding times to minimize waiting.
Disembark in New York City or Boston. After your cruise has docked, you will go through customs, where you will need to declare anything of value that you brought with you and anything valuable that you may have purchased on board the ship.
