Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

Smallest leg room I've ever had on a plane.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

The gate agent was most helpful in getting me on to fly standby. I greatly appreciate it.

bulkhead seat had very little legroom - even in bsiness class.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Sorry I didn't realize I was writing a review for each leg. Please see my previous review - it applies to the entire flight, not just a single leg.

Copa staff at PTY and one particular crew member were unhelpful & rude.

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

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

Some of the Air hostesses are not that friendly. Need improvement

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

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

horrible service, food was an embarrassment, no charging for cellphones, stay away
