Terrible. Would never fly again. Took them several hours to prepare the plane and and reached my destination 4 hours late.

Our boarding was delayed due to two flat tires, but I appreciate the focus on safety. I also appreciated the additional offerings for drinks which never happened before except on Hawaiian Airlines. The hospitality is fantastic! Glad I upgraded to premium seats for the extra leg room as I was getting frustrated when the person in front of me was very restless and kept shifting. Otherwise, it was a fantastic experience.

Had to sit and wait to get off the plane for closeto a hour. My son also flying to a different destination that day also had like a 2.5 hr delay

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

Could not check in online - had to get boarding passes at the ticket counter and our daughter got bumped off our connecting flight. NOT OK!

I needed more space to sleep on an overnight flight.

Our flight time was drastically changed which caused us to lose a day of vacation

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.

Only issue was the 2 hr delay after an 8 hr layover. Very long day.
