Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience.

6 hour delay including one after we were boarded. Horrible experience.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Everything was Okay. I was disappointed our luggage didn’t arrive with us and came in a flight 7 hours later. Representative said the will be delivered to the hotel. They have not arrived 24 hours later

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

Food TERRIBLE! In First Class- so bad - why was it so much better 20-30 years ago? Comfort-awful-would rather have the old, plush First Class seats than the new hard - too short seats in the new pods -would advise avoiding Delta for any International Flights.

7 hour delay for mechanical reasons Handled badly by crew and delta personnel

In thirty years of traveling, mostly with Delta, this was the worst day ever.

Copa definitely offers better service and price than other airlines.

Copa crew is almost never great in terms of service.

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.

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

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

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

Paper boarding passes needed, so you need to add the time at the kiosk or desk to get them at the airport

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

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

The sits were very hard and after an overnight flight my back was hurting. The food was very bad and poor quality, I was very hungry but I could not eat the food, I tried but the it was so bad , I don’t think my dog would have eaten it either. No kidding?!!! The Crew was lovely, the bathrooms were spacious and the entertainment was good. When I arrived in Madrid I was given the incorrect instructions by the woman who was at the desk for connecting flights information for LATAM airlines. Due to this I missed my flight and my luggage was lost. Consequently I had 3 passport checks and security checks in and out of Spain!!! The terminal T4 and terminal T4S are a different thing And they are very far apart. My flight was scheduled to exit at T4S and they send me to T4, I went to T4 they send me back to T4S and I had yo take a train and check in and out this time I was exhausted and wanted to cry. Eventually a crew member of LATAM felt compassion for me and saw my predicament, she said I had no time to go back to terminal T4 again so she rescheduled the flight. My baggage was lost and I had to go to try to find it at midnight. It was a real nightmare. Just thinking about it makes me angry. This Airport in Madrid is not easy to navigate, so please give people some real assistance and assurance. I SHOULD have not missed my flight There was plenty of time. It was miss information of people who don’t care, don’t read and don’t listen and unfortunately that is their job. Not happy at all

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

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

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.

Airline lost my luggage and after 20 days it has not been returned nor refunded any money.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

Was a good flight , well served by the flight attendants. Boarding went smoothly, flight was smooth.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

Lady was a bit rude during boarding and I was being nice to her.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

No complaints. Good WiFi, great crew and excellent speedy baggage claim

Flight was on time, no drinks served on the two short flights. Comfortable seats.

This time there was nothing to be better, really! Boarding on time, taking off on time and arriving earlier. The only complain is about way too long line at pre-check security point at DFW. But this is the airport’s problem, not American Airline.

3 hours late. Second consecutive time this month that a flight from DFW was delayed 3+ hours.

I had a first class lie flat seat which broke within 20 minutes of takeoff. I had to sit at an uncomfortable position for 9 hours, and the crew was terribly inconsiderate. I ate in the aisle, didn't have any entertainment due to none of the electricity working on my chair.

I was bumped to first class so I got some food. It was OK. Entertainment is whatever you bring with you since there are no seatback screens.

Dallas Hub. American taking ownership for their screwups instead of blaming their contractors and customers, trading their people, their call in service, reservation agents and their ticketing process. Make sure wheelchairs are available especially when the request is in their record.

American Airlines should be ashamed of their performance on AA1506 on August 14th from DFW to IND. First of all, after we got to the originally assigned gate C7, we were notified with too little notice for a first-flight out situation that the flight would depart from gate A25 in an entirely different terminal -- not just a gate or two away from the original gate. That was the first hiccup that started our day off poorly. It just got worse. Let it be known that the flight crew and gate agents were all as helpful as they could be during all that followed. However, the flight was a horrible mess of an ordeal. The plane was warm and uncomfortable on a hot Dallas morning when we boarded. And apparently we had to get underway for the a/c to be powered up. There was no other explanation for why we had to sit there in the heat. But before we could power up, some paperwork had to be completed, if we heard the announcement clearly enough. Then a "minor" maintenance issue had to be fixed -- but it was enough of an issue that we all had to deplane while it was being fixed, apparently because it was "too warm" on the plane for us to sit there in case the "minor" issue took too long to fix. And after we all finally deplaned and were hanging around the counter for news about when we could reboard, then a flight attendant came up and notified the gate agent that there a passenger at the rear of the plane had caused a major spill of some sort getting up and out of the plane. Turns out that was a bigger and longer delay than whatever the initial mechanical issue caused. According the gate announcements, the mechanical issue had been fixed relatively quickly in due course. But a seat was soaked and had to be cleaned up by a spill. A subsequent announcement then said that the seat belts were affected by the spill and had to cleaned. Then, either the seats or seat belts or both had to be replaced. At each of these announcements, the phrase "we're trying to get maintenance here as soon as we can" kept coming up. Clearly the gate agents were as frustrated as the passengers. After all was said and done, a minor mechanical issue and a major cabin spill issue caused a 3+ hour delay in our flight. American Airlines should be ashamed of its performance on this flight.

Go back to the old days of boarding the rear of the plane first to reduce congestion!

We received a flight delay notification over 24 hours before the flight, but it seems American didn't do anything in that timeframe to get the flight back on schedule. Gate agents were still determining when our plane would arrive. Didn't have catering ready to go when our plane did arrive. Flight attendant timeout before we left. There was a flight attendant on board who could work the flight (trained on that aricraft type and was within hours), however American chose to wait for a backup to arrive, which delay the flight further.
