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

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

Not very good, they nickel & dime you for better seats & pay extra for the checking in bag, bad service all the way around

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

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

Check in of my luggage which needed to be paid for was excellent. Thanks to Nora

As usual, LATAM tried to rip me off as a Gringo. They ignored the fact that having paid for my assigned seats, I was entitled to one free luggage per person, up to 10kg, and tried to charge me USD40 per item. While they ripped me off by $160 on my outbound flight (4 luggage pieces, which should have been free), I vehemently protested this time around. Note that they only request this from gringos, not from Spanish speakers. LATAM behaves like a racist extortion organization.

This airline is full of junk fees. After paying to get my kids to sit with me, we were asked at the gate to check in our roller bags and pay $40 for each one. Peruvian passengers all took their roller bag in the plane. I don’t appreciate airlines who spot the gringos to tax them more.

Pros: "Nothing as we could not take the flight."
Cons: "Allowing the option to change your ticket date, but failing all debit and credit cards payments offered, actually means that they are not allowing flight changes due to COVID related issues like they say they do. We had to book new tickets with another airline to get home."
Cons: "I needed to change my ticket and Kayak had another agency issue the ticket. Kayak does not change tickets and the third party and the airline said only Kayak could make the change. Having to purchase a whole new ticket from the airline, save the money and frustration and avoid Kayak and just book directly with the airline. The ticket would have and should have been changed with no fees. $325 lesson learned."
Pros: "Yes"
Cons: "Serve some type of beverage with out charging a lot"

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.
