Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Delta is a cut above the others in customer service.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

No headphones given for inflight entertainment. I missed my flight from the previous day and the customer service agent tried to extort an additional $100.00 US from me for missing my flight. Really?!

It was reasonably comfortable trip considering its duration (7 hours). Crew was very good and friendly, seats very more comfortable than other planes. Only negative comment would be that the bathroom light did not get its full brightness 🙃

The flight was delayed about 4 hours without any explanation. No wifi or entertainment at all on planes. Had to pay for checked bags I was allowed according to reservations.

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

Well the airline was fine. The only thing is I was charged for a checked in luggage. But when I reserved the ticket it showed a check in bag allowed. Who can I get in contact with for reimbursement.? The airline said I had to speak to whoever I booked ticket with.

I loved my experience. Very safe, Very informative and very friendly.

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

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.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Paid $35 and not able to access the internet at all.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

The boarding crew was incredibly helpful getting me on an earlier flight

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

I receive a service for what I pay, so it is fair.

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Terrible, We had to stay in Bogota for two days due to weather but the airline did not provide for the same day flight. Only two days later

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.

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.

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.

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

Boarding, crew and food. Seats are too small Love Avianca
