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.
