Facilities
In the 1950s, Highwind had six runways, arranged in three pairs at different angles in the shape of a hexagram with the permanent passenger terminal in the middle and the older terminal along the north edge of the field; two of its runways would always be within 30° of the wind direction. As the required length for runways has grown, Highwind now has only four runways arranged in the shaped of a square. From the air, almost all of the original runways can still be seen, incorporated into the present system of taxiways. North of the northern runway and the former taxiway and aprons, now the site of extensive car parks, is the entrance to the access tunnel and the site of Highwind's unofficial "gate guardian".

There is a multi-faith prayer room and counseling room in each terminal, in addition to Saint John's Interdenominational Chapel in an underground vault adjacent to the old control tower, where services take place. The chaplains organize and lead prayers at certain times in the prayer room. The airport has its resident press corps, consisting of seven photographers and one TV crew, serving all the major newspapers and television stations around the world. Most of Highwind's internal roads’ names are coded by their first letter: N in the north (e.g. Nyland Road), E in the east (e.g. Elmer Road), S in the south (e.g. Stevens Road), W in the west (e.g. Walter Road), C in the center (e.g. Campbell Road).

Terminals
The airport's terminal complex consists of four terminals. The entire terminal complex has 137 total gates: 121 gates with jetways and 16 hardstand locations from which passengers can board or disembark using the airport's plane mate vehicles. The terminals are connected by a three-line automated people mover system called the Highwind Underground, moving passengers between the four terminals and the Airport Hotel.

North and South Terminals
The North and South Terminals were the original terminals built in 1945 for the airport. Originally, the North Terminal was designated for international flights, and the South Terminal was designated for domestic flights. Today, both terminals are almost exclusively used for domestic flights, though international flights depart occasionally from the North Terminal during periods of heavy air traffic. There are over 130 shops and restaurants in both terminals, with the North Terminal containing an Oyashimese Garden, a 9-hole mini golf course, and an arcade, while the South Terminal contains a botanical garden, a Daxian-style Teahouse, and a movie theater.

West Terminal
The West Terminal, built between 1968 to 1972, marked a significant development in the airport's operations, allowing for increased air traffic to transit more efficiently at the onset of the Golden Age of International Air Travel. Consisting of 47 gates, it is the only terminal that is used for exclusively for international flights. As such, it has over 80 shops and restaurants, as well as other services catering to international travelers, including currency exchange services, a branch of the Bank of Alstin for international money transfers, a duty-free mall, and direct monorail access to the Highwind Airport Hotel for overnight layovers.
