Located just three miles east of downtown Phoenix in Maricopa County, Arizona, Phoenix Sky Harbor International Airport is the state's largest and busiest aviation hub. Serving over 50 million passengers annually, it ranks among the busiest commercial airports in the United States and globally. The airport covers 3,400 acres with three parallel runways, serving as a primary gateway to the American Southwest.
Sky Harbor is organized into two active passenger facilities: Terminal 3, named in honor of Senator John McCain, and Terminal 4, named after Senator Barry M. Goldwater. Terminal 3 handles mostly domestic carriers like Alaska, Delta, Frontier, and United. Terminal 4 serves as a major hub for American Airlines and a base for Southwest Airlines, while also accommodating all international flights.

Lost, delayed or damaged baggage at PHX
If your checked bag doesn't turn up on the belt, act before you leave the baggage-claim area — that's where every airline keeps its Baggage Service Office.
- Go to your airline's Baggage Service Office in the baggage-claim hall of your arrival terminal.
- File a Property Irregularity Report (PIR) and get your file reference (WorldTracer) number. Keep your bag-tag receipt and boarding pass.
- Track it online using that reference on your airline's baggage-tracking page — most bags are located within 24–48 hours.
- Claim your essentials. On delayed bags airlines reimburse reasonable interim purchases (toiletries, clothing) — keep receipts. International trips are covered by the Montreal Convention.
- If it's truly lost (generally after 21 days) or damaged, file the claim at the same office — damage must be reported before you leave the airport.
Left something in the terminal (not a checked bag)? That's handled by the airport Lost & Found. Items left at a TSA security checkpoint are held by the TSA, not the airline.
