Finding Cheap Flights To Honolulu

Honolulu is served by Daniel K. Inouye International Airport (HNL), the primary aviation gateway to Hawaii and one of the busiest airports in the United States for passenger traffic. It offers an extensive network of domestic flights from the U.S. mainland, crucial inter-island connections, and a growing number of international routes from Asia and the Pacific.

The airport is the central hub for all travel into and within Hawaii. Key mainland U.S. departure points include Los Angeles (LAX), San Francisco (SFO), Seattle (SEA), Las Vegas (LAS), Phoenix (PHX), and numerous cities on the East Coast. Inter-island flights arrive from Maui (OGG), Kauai (LIH), Kona (KOA), and Hilo (ITO) with extremely high frequency. Important international routes into HNL include Tokyo (NRT, HND), Seoul (ICN), Sydney (SYD), and Auckland (AKL).

HNL is the main hub for Hawaiian Airlines. It is also a major focus city for Southwest Airlines for inter-island and mainland arrivals into Honolulu. All major U.S. carriers (American, Delta, United, Alaska) operate extensive mainland routes to HNL. International carriers like Japan Airlines, Korean Air, and Qantas also serve Honolulu.

To secure cheap flights to Honolulu, book mainland arrivals 2-5 months in advance, especially for peak travel times (summer, holidays). For inter-island travel into HNL, book 2-3 weeks ahead. Use flight comparison tools and set price alerts. Flying on weekdays (Tuesday-Thursday) for arrival is typically cheaper. Southwest's entry into the Hawaiian market has driven down inter-island and some mainland fares into Honolulu significantly. For the best deals from the mainland, look for sales on Hawaiian, Southwest, and Alaska Airlines. Consider open-jaw itineraries (flying into one island and out of another) to avoid backtracking when Honolulu is your arrival point.
