Arriving at Phoenix (PHX) FAQs
Cheapest Economy Fare (ECN) is a way of describing the lowest available economy-class ticket for a route, often including basic economy with restrictions. When arriving from Phoenix Sky Harbor International Airport (PHX), ECN fares prioritize price over perks like seat selection and flexible changes.
