My husband unfortunately had a very large lady next to him who did not fit in the seat and had to have the armrest up so she was partially in his seat and she also had horrible BO

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.

The Boeing 737 plane is old with narrow seats and tiny lavatories. The flight was delayed for over 2 hours. The flight attendants were discourteous.

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 offered water, no snacks provided, and it was cold on the plane, everyone was wearing sweatshirt or jacket in June. I asked for blanket, but crew said they didnt have anything and would turn the heat up, that didn't happen, so for 6 hours I remained cold.

One of the stewardess, Tre, went above and beyond to ensure my comfort!
