Despite its high passenger volume, lines at the check-in counters and security checkpoints at Phoenix Sky Harbor Airport are usually brisk and efficient, although during busy periods (spring break, holiday weekends, etc.) you should anticipate longer waits and arrive at the airport 30 to 60 minutes earlier than you would otherwise. Because Phoenix is a hub for Southwest and American Airlines, it has direct flights to most major U.S. cities and a number of international destinations elsewhere in North America (Calgary, Cancún, Edmonton, Guadalajara, Mexico City, Puerto Vallarta, Toronto, Vancouver, and San José, Costa Rica, among them), as well as nonstop service to London on British Airways.
Sample flying times from major cities are: one hour from Los Angeles, three hours from Chicago, and five hours from New York City. Keep in mind that several destinations have only seasonal nonstop service from Phoenix (usually from midautumn through midspring).
Major gateways to Arizona include Phoenix Sky Harbor International (PHX), about 3 miles southeast of Phoenix city center, and Tucson International Airport (TUS), about 8½ miles south of Tucson's central business area.
Phoenix Sky Harbor International Airport is one of the busiest airports in the world for takeoffs and landings but rarely suffers from congestion or lengthy lines. Its spacious, modern terminals are easily navigated, with plenty of dining options as well as free Wi-Fi. Sky Harbor's three passenger terminals are connected by the free Sky Train, which runs regularly throughout the day and also links to the 44th St./Washington METRO Light Rail station. Shuttle vans to the rental-car center stop outside each terminal.
Tucson International Airport has one terminal that has a smattering of restaurants and free Wi-Fi. Although it services far fewer passengers per day than Sky Harbor, it does offer nonstop flights to Chicago, Atlanta, Denver, and a number of cities around the western half of the country.
