This research examines the relationship between seven airport service dimensions (Access, Services and Facilities, Dining, Shopping, Service Personnel and Security, Environment, and Immigration and Customs) and overall passenger perceptions of service quality. The study used convenience sampling collecting data from a total of 304 travelers who were passengers at four major international airports in the West Coast region of United States – Las Vegas McCarran International, Los Angeles International, San Francisco International, and Seattle-Tacoma International. The data was collected online through Qualtrics with a self-administered questionnaire and it was analyzed using multiple linear regression.
