Walking the Airport

Due to construction, a portion of Terminal 1 is closed on both levels. The best way to get from the International Terminal to Terminal 1 Gates B (Gates B1 – B27) is by walking. The best way to get from the International Terminal to Terminal 2 (Gates C1 – C11 and D1 – D18) is via AirTrain. The best way to get from the International Terminal to Terminal 3 (Gates E1 – E13 and F1 – F22, United) is by walking. However, AirTrain is your only means to and from the Rental Car Center. 

Information Booths

Information booths, staffed with friendly volunteers, are located throughout the terminals. Please view the Information Booths map for exact locations. Language assistance is available.
