TravelBank, a business travel app, released a study of the best and worst airports for business travelers, and McCarran International Airport topped the list as the best airport in the nation. The airports were scored according to a variety of factors, including on-time arrivals, airport transit, airport parking prices, quality and service, and average hotel price. McCarran’s proximity to Downtown and its American Express Centurion Lounge rounded out the winning amenities. Airports in Phoenix, Salt Lake City and San Diego also made the top five. The five worst airports included three in the New York City area (LaGuardia, Newark and JFK) along with San Francisco International and Los Angeles International.
