Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

My experience with the united usually is a really good one. But however, on this particular trip going back to Hawaii from Manila, our flight had gotten canceled. However, the crew handled everything just right, but the Specialist team did not take care of their first class customers very well, Because I lost my first class seat and witch I'd paid for $3879.79 and ened up flying.... Economy on the way back and I have a medical condition to ware i cant sit in Economy seats for very long....And I have to fly first class for a reason, but they told me there was nothing they could do about it. But yet they have an itinerary to follow And It looks to me like they just let anybody grab those first class seats before they took care of the people that have already paid for them!! So when a flight is canceled, they should take care of their first class ticket payers... First because we pay big money for those seats And we count on those accommodations in those benefits... For real good reasons, that's why we pay that kind of money. I'm expecting at least half of A. Refund back to my credit card for you for this...And if I don't get it, I'll never fly united again, it's sad that this happens And some things are out of our control, and I totally understand it, but at least handle your first class holders first before all.. That is what we pay for.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.
