A direct flight may touch down en-route for re-fueling, or to pick up and/or drop off passengers.
In these instances you're not normally required to disembark and the flight is still considered to be a direct flight.
A non-direct flight may require a change of aircraft en-route while a non-stop flight will take you directly to your final destination airport without stopping.
On occasions we may have to amend the operating route for operational reasons, including a touchdown. You will be notified to you as soon as possible and, at the latest, at check in or at the boarding gate.
If you are travelling to the United States, you will be required to disembark your aircraft, collect your baggage and pass through US Immigration and Customs at your first point of entry into the USA.
e..g If you are flying from Manchester to Orlando via Atlanta, you will clear immigration and customs in Atlanta.
