The airport has 2 terminals. The larger modern terminal on the left side of the airport is used for the majority of international flights. This building is large, spacious and very clear.
Arrivals is on the right side of the terminal, check-in counters on the left and security on the first floor.
The small old terminal can be found under the control tower and serves some of the smaller airlines flying to the surrounding islands.
The terminal is not marked on the ticket and you won't find it marked on the departure boards either. If the departures screen shows check-in counters 28 to 39, you will need to go to the old terminal. All other counter numbers can be found in the new terminal.
Transfer between flights
The airport is one of the relatively important transfer hubs within the Caribbean region.
You will often connect in Antigua en route from the southern Caribbean islands (Barbados, St. Lucia, Dominica) to the northern islands (St. Martin, Tortola, Turks and Caicos).
If you have both flights on the same booking (the transfer is guaranteed by the airline), you will not leave the transit area and your luggage will be transferred automatically. You do not go through passport control during the transfer, but only through security.
If you are connecting to flights operating from the old terminal (typical destinations are Montserrat, Barbuda or Anguilla), you must always go through immigration, collect your luggage and walk to the old terminal.
