My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

Comfort, don't think I will fly United again not worth the money to be packed in like a sardine.

Overall, the flight was good. Lounge access should be with all business class tickets.

Staff are not helpful, our flight was cancelled due to aircraft problem

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.
