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

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!

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

We were given vouchers we couldn’t use with a 5.5 hour delay

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.
