Seattle airport is nuts compared to PHX. Be patient when you land.
GlennFlew with Alaska AirlinesPHX-SEAJul 2024
Be prepared for the disorientation of SeaTac as the entire terminal appears to be under construction. It’s unnerving.
JamesFlew with Alaska AirlinesPHX-SEAMay 2024
the flight from phoenix to seattle was crowded but the crew was great. The plane would have been more comfortable had they flew the 737 max on this leg. I had an aisle seat at the back and throughout the flight had a line of passengers bumping into me due to the narrow aisle and people attempting to pass each other.

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The worst flight of my life. Never will I fly frontier again

Landing in terminal 2, but my luggage is terminal 3. We (and others) were looking for it in terminal 1. We probably missed the crew broadcast, but the communication could have been clearer for non native (or elderly) passengers.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!
