What Terminal Is Frontier Airlines at PHX? Here’s the Answer Knowing which terminal to go to is crucial if you're flying with Frontier Airlines out of Phoenix Sky Harbor International Airport (PHX). For the majority of its domestic flights, Frontier flies out of Terminal 3. With locations for boarding, security, and ticketing clearly designated, this terminal is contemporary and user-friendly. Convenient elements like dining selections, seating sections, and digital signage make it easier for travelers to locate their gates.
However, Frontier uses Terminal 4 for a few foreign destinations, including Cabo San Lucas. Numerous more airlines also use this terminal, which is the biggest at PHX. You will normally check in on Level 2, close to the British Airways counter, if you have a reservation for an international Frontier flight. To prevent confusion and make sure you're in the right terminal with plenty of time before departure, it's a good idea to confirm your flight details beforehand.
Plan to go to the airport at least two hours before domestic flights and three hours before foreign departures to ensure a more seamless travel experience. Frontier has stringent baggage and boarding regulations, and its check-in desks close one hour prior to departure. You may start your trip more leisurely and save last-minute stress by planning ahead and knowing which terminal to go to.
