Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

Boarding was confusing with a delayed flight because there was no English translation

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

Lost ,y connection due to a mechanical delay, huge line to get new connection and vouchers

entertainment was not good; the shoulder strap on Business class seat did not sit well across the body (more like across the neck); the food was not hot and the special meal promoted by insert in the menu was not available to us

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

Economy travel is really hard with no room to move especially when the person sitting beside you is an XL or XXL size person who if moving could hit your face

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

I was denied lounge facility at airport. Explanation was not satisfactory.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Boston to Doha was great but Doha to Dhaka was the worst experience.

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.
