Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

Was unsure of this flight due to high winds in CVG from Hurricane Helene. Crew did a great job of getting us to CVG safely.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

More up to date movies and a live TV option like ESPN, Fox News or CNN. All they had were movies and Spotify Music and some games. Also, wifi on international flights isn't free for Skymiles members like on domestic flights via T-Mobile.

No wifi on the long haul flight, food was trash and no vegetarian meal options

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

Overall, the flight from Atlanta to Orlando was acceptable, albeit delayed and the typical temperature issue on the plane (hot) which has become somewhat expected. However, the staff at gate B22 for connecting flight DL1562 was disappointing. And to clarify, there were two gentlemen behind the counter — one pleasant and the other, Larry. Without question, Larry should not be in hospitality. My wife and I were first in line and when Larry walked in behind the desk, my wife greeted him with “Hiii Larrry”. And while she can be bubbly at times, and I get that it was late, the conversation morphed as Larry asked if she was drunk. At first I assumed he was joking (still not appropriate) but he was not. Clearly he was having a bad day or maybe just hates his job. In all cases, his behavior was unacceptable and offensive. The only saving grace is that he was equally rude and dismissive to all of the surrounding guests as well—although, I’m not sure if that is a good thing or not.

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

Copa definitely offers better service and price than other airlines.

Copa delayed the fight three times. We ended up flying about 24 hours after the original time.

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

The personnel at the counter was very helpful. Everything ran on time.

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

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 .

Copa me elige como "voluntario" para cambiarme y poder enviar a una familia a la cual había sobrevendido los tiquetes. Finalmente me envían a las carreras con Avianca, pero Copa lleva mis maletas hasta Panama y luego las devuelve a mi aeropuerto de origen, dejandome sin mis pertenencias y además no asumen la responsabilidad ya que dicen que es problema de Avianca Literalmente vi cuando el avión de Copa se lleva mis maletas, sus funcionarios en Bogota, incluyendo la gerente local me aseguran la entrega en Miami, pero simplemente era para poder engañarme y dar el cambio de silla por sobreventa

It was fine. no food or entertainment , but was only a 40 minute flight.

Routine and on time flight with pleasant stewards and decent food. Nice experience!

It was a long and boring flight with no entertainment and no meal only a drink and very bad bag of chips

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta

No food optional ( they offer just pasta, no second option, the soda without carbonation, I asked for snacks and they said give a minute, I never got it) I believe they (crew) don't care about it (people)

The crew was amazing. The best in the last times. Great group of people.

Check-in was a total disaster, almos a full hour in the line

On time. At least they offer a drink and a small snack. Plane was clean

You delayed my trip three days for no reason other than your lack of preparedness, did not offer any compensation, including food or a bed. I couldn’t trust you so I moved up my return flight and lost another day at the end of my trip to hopefully make sure I make my next flight. I will never fly LATAM again. You have the worse accountability and reliability and clearly do not care that your clients have lives and what it cost to fly to another country.

I didn't realize they didn't have bathrooms on the plane. Almost had a very bad situation.

WiFi was not working from pos to Mia…. As well as they rushed us to the gate as if the flight was already here and leaving shortly when the plane never even arrived and took off until the scheduled time so then why rush us to the gate and have us thinking we will miss our flight.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

The First class experience was really good!! Customer service was excellent.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

Charlotte NC agents were great and ended up with decent seats after having to switch flights amidst Hurricane situation. CMH was a different story. Doors to flight closed 15 minutes before departure so we nearly were left behind. Flight crew were OK but nothing to brag about for sure

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

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

Always a great flight on AA. PHX to DFW and vise versa is always going to be a pretty full flight but the crew handles it phenomenally.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Airlines changed our originally booked flights. Our luggage was completely damaged.

I enjoyed it! In that case, I should have been offered this choice. On my first trip to Miami, I was asked to pay $320 for my luggage just for getting it totally broken. I cannot accept this situation at all!!!!

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!

I was surprised that they didn’t offer drinks at least even though it was an international flight.

$120 for a carry on bag !!!!!! Insane. Back-breaking seats. Do not recline. Food service is a disgrace. They give only water and a salty snack. Everything else has a price.

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!

My fly was cancelled so i run to the airport and fight for my fly Thank god at the end was good

Terrible. Flight was delayed without explanation, airplane was in poor condition (old, dirty) and crew was not in a good mood.

Definitely my worst experience. We booked a flight JFK - Cartagena with a layover at Bogota. My partner and I were on time for the boarding at 10:55pm. We were about to enter in the plane, literally, when one of the officer from the airline Avianca, took the passport of my partner to apparently « looked at his luggage reservation ». It made no sense, first the luggage was under my name, and then we went through all the controls at the airport. The person went back to the gate inside the airport, I followed my partner. The employees from the airline were rude and disrespectful. They were not explaining us what’s was going on. After 5 minutes of silence treatment. They told us that my partner was intoxicated (it was absolutely not true, they never conducted tests btw) and he couldn’t board in the plane and he will take the next one. They didn’t late us coordinated the trip, and not even let us say goodbye to each other. I was forced to take the plane to bogota and my partner to stay in NYC. It was traumatic. My partner had to wait 6h in the airport (night time) and he had to pay an additional ticket even tho the employees mentioned he was going to take the next flight. We are going to file a complain. It’s unbelievable. First and last time I will ever use this airline. I do not recommend.

Ok, but these people don’t give you nothing no snack no water

No water for a 5 hour flight entertainment not working seats with little room for knees when person in front of me reclined kept bumping my knees.
