Airport Information

Honolulu (HNL)

Daniel K. Inouye International Airport (HNL) is the principal gateway to the Hawaiian Islands, located just northwest of downtown Honolulu. The airport is unique for its open-air corridors and lush tropical gardens that allow travelers to enjoy the warm island breeze right up until boarding. It serves as a major hub for Hawaiian Airlines and offers a wide array of local dining options, including fresh poke and shave ice, ensuring a flavorful aloha send-off before your flight to the mainland.

Seattle (SEA)

Seattle-Tacoma International Airport (SEA), commonly referred to as Sea-Tac, is situated about 14 miles south of downtown Seattle and serves as a primary hub for Alaska Airlines and Delta Air Lines. The facility is renowned for its impressive art installations and the Central Terminal’s massive window wall overlooking the runways. For easy transit, the Link Light Rail connects the airport directly to downtown and the University District, providing a cost-effective alternative to rideshares during the city's notorious peak traffic hours.
