Lying or being beyond the Atlantic Ocean.
Crossing the Atlantic Ocean; as, a transatlantic flight.
crossing or reaching across the Atlantic Ocean.
A cruise that crosses the Atlantic Ocean. However, ships are no longer in a race to cross the ocean. Even Cunard's QM2 takes a leisurely six days to cross the "pond" non-stop. Today, stops in Europe, the Azores or the Canary Islands, and the Caribbean are often scheduled into transatlantic crossings.
The term transatlantic refers to something occurring all the way across the Atlantic Ocean. Most often, this refers to the exchange of passengers, cargo, information, or communication between North America and Europe.
