If all the airlines were ran so well. Staff very professional and kind.

Direct and non stop. We were late checking in but had paid for our luggage to be checked and they easily took the bags at the gate for us. We unfortunately had to take our bags through TSA and lost a few items...

The FTA in the JFK airport was so mismanaged. It needs improvement. Flight attendants should set age limits. In-flights snacks should provide two times instead one.

First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.

Pretty disappointing as we did leave Seattle two hours late.

1.5 hour delay boarding plus 1+ hour sitting in plane waiting for ground crew to load luggage and freight, made for 3:00AM arrival in Seattle.

The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

Worst part is being squashed in a seat ( I am not fat) and unable To get comfortable

Took forever to get on board. Flights was one hour late.

They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.
