I needed more space to sleep on an overnight flight.

Very good; ohana atmosphere and taking care of customer care

Flight was delayed an hour, so that was inconvenient. But they tried to make it up in the air, which I appreciated. Crew was very nice, service was excellent. Description of food didn’t quite match what was served, but it was tasty. 👍🏽

Really bad experience. Bad customer service from the check in process through the entire flight.

They were friendly, efficient and got our bags to us so fast at the end of the flight.

Wonderful staff who honored sleepy overnight travelers and still met needs quietly and quickly!

Wonderful respectful staff for a short flight late at night...lots of considerations all met!

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

1. On time flights. All of our, three separate, flights for three families were late 2. No food on the 5 1/2 hour flight. A substantial snack would have been good. 3. Seat upgrades are expensive 4. No place to move around or stretch on the 5 1/2 hour flight
