Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The plane was so outdated, that it made it uncomfortable. The temperature was hot during the whole flight

Some entertainment and food/snack service would have been nice

All the pessengers should be wait in a line útil the creo and piloto are arrived.

Planes seat could be bigger very uncomfortable for tall humans.

1 hour waiting for suitcases to come out traveling in business class and food in business class is a sandwich? Avoid Aeromexico .

No space reserved for anyone who didn’t have underseat in front of them. Made it inconvenient to get the backs secured. No inflight entertainment in the 190. Bring your own! Food was excellent and we were surprised to get a full breakfast.

Cons: "left Houston more than 2 hours later, arrive in Mexico over 2 am"
Cons: "El problema es que nunca pude cambiar mi vuelo y con ustedes fue imposible comunicarse para que me auxiliaran. Muy mal por ustedes no por la línea."
Pros: "The crew was amazing , the site is ok"
Cons: "I love Aeroméxico , thanks for de service and the food."
Pros: "Crew friendlynesd"
Cons: "Paying a little more attention to the seating. Not everyone was socially distanced. Seat rows were unequally distributed: some were all full others were too empty."

Everything was as you would expect in coach - fine. Flight was close to on time.

It was confusing because I got a notification that my gate was changed when in reality it wasn’t

It’s been some time since I saw the plane and the cabin that old and worn out.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

It was ok for the most part, it is missing something

It was a good experience, the flight was a little too long & the food was ok

Hostile flight attendants. Second flight with Jose so much better. Arrived 1/2 hour early. Thanks.

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

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

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay
