A
8.3 Very good
Pros:Seats were comfortable, area was clean.
Cons:I was in the center seat, my husband in the window seat. The aisle seat was occupied by a woman who looked to be around 300 pounds. She didn't fit in the seat so she required part of my seat and her legs mostly in the aisle. Okay....that was bad enough but just to make matters worse she neglected to apply her seat belt. I shuttered to think of what might have happened to her neighbors if we experienced turbulence.
A
7.3 Good
Pros:Everything was great EXCEPT for the wifi that cost $$$ and was slow and told me my device couldn't stream tv or movies. $10 not well spent

M
10.0 Wonderful
Pros:Traveling with a group of 11 was a challenge and we had a few bumps getting our whole group on the flight due to paperwork issues but the Captain and Crew were so helpful and fun. They took us under their wing and made us all laugh and smile. Great way to start a trip!!
Cons:The only thing that I didn’t like about this flight was having to use LAX. I wish I could have caught this flight out of Long Beach!
A
