I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

The flight was 6 hours delayed due to equipment problems, I had to spend my night in the airport terminal in tight quarters. A bag of chips was all they offered, Then I missed my connecting flight and waited another 2 hours. All in all that trip took me almost one day.

I like that they served a mail, I’m not sure about the in-flight entertainment. I didn’t really check. staff helped me with my luggage. Smooth boarding smooth takeoff smooth flight

Just a minor inconvinient with weather delay! but not Copa's fault

Copa definitely offers better service and price than other airlines.

This airline doesn’t five and dime you for everything. I do think that a checked bag should be included in every fare.

The seats had plenty of leg room and the staff were very nice.

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

More information is needed on travel Requirements in the check in website

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

United ground crew and pilots are friendly. The in-flight staff (flight attendants) are the worst in the world. Multiple trips, always unpleasant, combative, use implicit threats to not allow for a discussion on their decision. Authoritarian. This seems to stem from an internal corporate wide policy as I doubt that United is intentionally searching for people that are not fit for customer facing positions. I will not fly United again. Good luck fixing your business

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?
