Airline reviews

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

Poor, the airline was not able to help me move flights.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

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.

The service was good but the food was a NO

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

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.

The seats were uncomfortable. The service was poor. We bought internet for my family and myself and it didn’t work. The charger for our phone didn’t work. The service seemed like they were tired and exhausted and seemed a bit upset. It was not a good flight. Our flight from miami to Qatar was great but from Qatar to Tokyo was simply awful

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

The staff was great and probably that's the single most thing that distinguished this particular Qatar flight from my average typical experience. They genuinely wanted to please you and do their best.

It was ok, not much more can be said, as long as airlines/aircraft manufacturers insist on cramming in as many seats as possible....best of a bad situations, seats are simply too uncomfortable to sit in for more than a few hours. Lack of flexible headrests not a help on long overnight flights either.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".
