Traveling between Terminal 1 and Terminal 2 at Daniel K. Inouye International Airport (HNL) in Honolulu is very quick, taking approximately 3 to 10 minutes depending on your method of transport. The two terminals are physically connected and are only about 150 meters apart. If you choose to walk, there is a shaded pedestrian sidewalk on the ground level that takes about 3 to 5 minutes. For those with heavy luggage or mobility needs, the free Wiki-Wiki Shuttle buses run "airside" (post-security) and "landside" (pre-security) between the terminals every 2 to 5 minutes, with the actual ride taking only about 2 minutes. Terminal 1 is primarily used by Hawaiian Airlines and Southwest for inter-island and some domestic flights, while Terminal 2 is the main international and transcontinental hub. If you are transferring between these terminals for a connecting flight, you typically do not need to clear security again as long as you remain in the "sterile" area and use the Wiki-Wiki Shuttle. This makes HNL one of the more "transfer-friendly" major airports in the Pacific, assuming your bags are checked through to your final destination.
