It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

My tray was broken and instead of being moved I was provided blue tape.

One hour delay. No Wi-Fi. Old aircraft. Nasty food

Was unable to check in online within 24 hours of departure

Overall, good flight and quiet cabin! Took the red eye home from Honolulu to LAX!

Couldn’t check in online. Unsure of terminal. Missed flight by minutes due to confusion and not being able to check in online pre flight.

Grumpy and rude gate attendant who was unwilling to help anyone who asked him for assistance. Too little leg room.

The food was lame for an almost 5 hour flight, but overall I had a good experience

VERY short notice (<24 hours) flight delay by 6 hours. Had to reschedule and pay more to book with another airlines.
