We were made to check our carry-on luggage because it did not fit the measurements. That’s what we were told, but I saw plenty of carry-on luggage on the plane that was the same size as ours

Flight Crew Review The crew was absolutely amazing from start to finish! They were friendly, professional, attentive, and genuinely made the flight feel comfortable and enjoyable. Every interaction was pleasant, and they went above and beyond to make sure passengers were taken care of. You could really tell that they cared about providing great service. I truly appreciate their kindness and professionalism and would be happy to fly with this crew again!

stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

I would like a glass of wine or some kind of alcoholic drink.

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Boarding time was delayed in more than two hours. Then another hour on the ground before take off. Wi-fi was not working throughout the flight. Business class in even rows by the window are not so comfortable. And space for feet always feel tight. Had a meeting in New York early the following day with multiple people and had to request a delayed start.

I so appreciate the crew members on each flight of United. They are outstanding.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.
