Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

It was terrible, I sat next to a person with a cat, I'm allergic to animal dander, my discomfort was extreme

Seats were really tight and the seat belts did not give enough slack.

Great list of movies, seat was generally comfortable, but not much shoulder room. The fresh baked cookie mostly made up for the lack of variety with the meals, which were all tomato based.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Not being in the back row and having to pay for a better seat

Have veg meal going forward . Other than e everything was excellent !!!

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

Seemed roomier than most US domestic airlines and they served food.

it was great! Boarded on-time, reasonable leg room, pleasant staff, decent food. The only thing is we were directed to Terminal 2 when the gate was actually in Terminal 1. Smooth ride. Landed early. Got off plane easily and quickly.

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

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

So many hours of flying without salty food is a shame and the fact that they want to sell it to you seems like a rip-off

This airline makes you check in in one terminal and then you have to walk to the other terminal. Its messed up

Copa crew is almost never great in terms of service.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.

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.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

The flight got canceled last minute with no explanation or refund, I had to rebook for a different day

from Boston to Washington was good but return to Boston was terrible, Gate was changed and plane was so uncomfortable, I thought it would crash 🙈🤦‍♀️ also when I showed my bording pass they didn't know where to send me and finally gave me direction and at the plane they said to find free seat somewhere😬🤦‍♀️🫣

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

Flight attendants on American Airlines are rude very harsh with their time of voice. Nearly identical experience as spirit airlines. However, from Spirit Airlines, you expect this level of mediocre service. You do not expect this from the big three..

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

The plane had maintenance issues and didn't leave after 72 hours

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

So so, you feel like you have to pay for everything each time

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Felt very cramped in the back of plane. There was an hour delay for take off sitting on the runway, but we did arrive on time. They charge $120 for carry on bag and backpack at the airport its ridiculous.

Almost we lost our connection from Bogota to Aruba 🥴 Because we get out late from the plane of Medellin

Same experience, very poor food, drinks or entertainment while flying. There are some products offered to buy but only using debit or credit cards . No friendly for seniors or people without cards.

Poor In food , poor in entertainment , passengers don’t get for free not even water

It’s very nice, the only thing is that we have to purchase food.

Our flight from BOS - BOG was delayed 10 hours because they were waiting for a Flight attendant to fly from Miami. They lied and said they would give us food and hotel. That was a straight Lie! It never came! We were in the airport for 13 hours with Two babies. We were on the plane 7 more Hours. When we asked to get diapers from our checked luggage, Jorge in Boston told my wife she should have planned better. Meanwhile, the 10 Avianca Employees Sat there and did nothing for 13 hours. Yes, we planned for 10 hours with the wait and the flight, not 20 hours JORGE! If this was an American company we would have got a refund! But they are not up to American standards. The kicker is they apparently needed the 3rd stewardess to serve the food. Guess what? It was 4AM when they tried to serve the FOOD! Everybody was asleep by then! Ridiculous! Never Again!

Old planes rude workers no tvs seats don’t go back and overpriced
