Hey, I am Jerry and I recently visited Frontier Airlines PHX Terminal offers a straightforward, no-frills experience. The terminal is generally clean, with basic amenities such as seating, charging stations, and a few food options. Security lines can be busy during peak hours, but overall, the process is efficient. The lack of upscale services reflects Frontier's budget-friendly model, so travelers should expect simplicity over luxury. Overall, it's a decent choice for those looking for a quick and budget-conscious airport experience.
