At Daniel K. Inouye International Airport (HNL) in Honolulu, Hawaiian Airlines operates primarily out of Terminal 1. This terminal is dedicated almost exclusively to Hawaiian Airlines' inter-island, domestic U.S. mainland, and some international flights. Terminal 1 features the Mauka Concourse (Gates A13-A20), which is the airport's newest and most modern facility. If you are flying with Hawaiian Airlines, you will check in and drop your bags at the Terminal 1 lobby. However, it is important to note that some international arrivals may be directed to the International Arrivals Building in Terminal 2 for customs and immigration clearance. For most departures, though, you will stay within the Terminal 1 ecosystem, which includes the Premier Club and various dining options like the Wailua Bar & Cafe. The airport provides a free "Wiki Wiki Shuttle" and a newer electric tram service to help passengers move between Terminal 1 and the various concourses of Terminal 2 if they have a connecting flight with a different carrier.
