Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

Plane never left the ground. Mech issues - entire trip was rerouted through united.

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

I liked everything, this was classed as premium economy but it was much better than Lufthansas business class. Lovely staff, comfortable plane and an excellent seat arrangement. A very pleasant surprise.

Staff encountered friendly and helpful. Flight delayed 1 hour due to mechanical issue, but made it through Atlanta immkgration and security in plenty of time,

Basic experience, we were delayed causing less time to enjoy our destination and on the way back, we boarded when the flight should have been taking off.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

Issues with plane led to multiple gate changes and chaos. Very little communication from the ground crew led to cranky passengers.

I flew business class, at breakfast I asked for a small bottle of olive oil instead of butter and the flight attendant responded with a negative gesture.

They didn't even give us water, everything was sold

They should at least offer water like other airlines, which seems like a humanitarian gesture to me

They gave me an upgrade but charged me for my bag. I felt abused because this had never happened to me before with an upgrade with another airline.

Well. It is a no frills airline. Annoying is that even for the long-haul everything has to be paid for separately. Once you add up the extras the flight is getting to expensive. Then one might as well fly with a legacy carrier which provides far better comfort. Changing flight at MAD airport is a nightmare. The worst airport in the world. Poor signposting, poor passport control, poor security check and long queues. I had 2h transfer time and spend in queues almost 1.5h

All flights with Air Europa you arrive late to the connections of other flights, I missed my train, I had to pay for my train again, the crew are antisocial, you are paying for a service, it is not free, thanks to the travelers they are there, it is the last time I fly with them,

Terrible experience - we won’t be flying with Air Europa again

The crew was not kind , just doing their job but very cold people

The crew was caring and attentive in making my flight comfortable as I was travelling with an injury.

The plane was over an hour late taking off... the plane was rather tired looking, seat cushion was thin and uncomfortable, the sound on my entertainment system wasn't working... crew are not friendly.

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

Happy and nice crew and the atmosphere is very easy and calm. I got a wonderful travel with UA this time

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Using the media screen in economy class is a disaster

I have ordered Hindu or Indian vegetarian food, to my surprise they did not find any such request. All I ate during the flight was 2 pieces of bread. The airline hostess was completely rude and racist. She promised one apple and I asked he four hours of promise and she denied saying am not nice to her. Europeans seems to be having racism issues with Indians. I will officially launch complaint with Indian and USA governments They made to starve, I recently got open heart surgery and I am diabetic patient

It wasn’t bad but it was not excellent either. The airlines are trying to save as much money as possible and we are paying price for it. Flying is not as it used to be.

Delayed take off but I think they waited for passengers.

The staff was not at pleasant as those on the first leg of our trip.

We had a 3 hour delay and then a long taxi to take off. It would have been helpful for the pilot to have communicated more about what was going on. There was no A/C during the wait, and the cabin must have been more than 85 to 90 degrees. The crew gave water to the people in the front but by the time they go to the back of the plane they stopped giving out water. Eventually I went back and asked for some in the rear of the plane (for a second time). The food was close to inedible. I thought on an Italian flight that the pasta would be better than the chick, but honestly, a Swanson's TV dinner would have been better. I had a bite or two to keep my blood sugar up, but basically I couldn't eat it.

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

Terrible. They canceled 2 flights and then sent everyone by BUS from Rome. They should make amends by offering some sort of compensation.

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

We ordered a gluten free meal and never got it!

The seats are horribly uncomfortable. We were in premium economy and paid a premium price yet, the seats were the worst! You could feel every structural bar in the seat, there was no padding, no amenities kit, and the leg rests were broken. Duct tape was holding another seat together. When we arrived at our final destination, Venice, my suitcase was ripped open, and my clothes were about to fall out of the bag. I would’ve been more comfortable if I flew a paper airplane across the Atlantic.

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

Seats weren’t comfortable. Both of our seat backs were either almost straight vertical or laying back into the laps of the people behind us, which is a weird angle to try to get some sleep even on a plane. No in between. Also, neither seat would spring forward like they should.

The flight was great, smooth and even a little ahead of time.

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

The crew did not really interact with me which was no problem as I was fine. I did see that they were somewhat short with some passengers but that was not common. Just in general, they did not seem friendly - no requirement to be so but I am used to a friendly crew on most flights. The food was just ok but with a flight that large, I would think it hard to make something more elaborate.

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.
