We were not allowed to carry a bottle of water onto the 8 hour flight.

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

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

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

reliable, relatively relaxed, with helpful staff in all 8 flights we had on this trip. They are solid even though we did not have special seating or status for the flights.

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The sits were very hard and after an overnight flight my back was hurting. The food was very bad and poor quality, I was very hungry but I could not eat the food, I tried but the it was so bad , I don’t think my dog would have eaten it either. No kidding?!!! The Crew was lovely, the bathrooms were spacious and the entertainment was good. When I arrived in Madrid I was given the incorrect instructions by the woman who was at the desk for connecting flights information for LATAM airlines. Due to this I missed my flight and my luggage was lost. Consequently I had 3 passport checks and security checks in and out of Spain!!! The terminal T4 and terminal T4S are a different thing And they are very far apart. My flight was scheduled to exit at T4S and they send me to T4, I went to T4 they send me back to T4S and I had yo take a train and check in and out this time I was exhausted and wanted to cry. Eventually a crew member of LATAM felt compassion for me and saw my predicament, she said I had no time to go back to terminal T4 again so she rescheduled the flight. My baggage was lost and I had to go to try to find it at midnight. It was a real nightmare. Just thinking about it makes me angry. This Airport in Madrid is not easy to navigate, so please give people some real assistance and assurance. I SHOULD have not missed my flight There was plenty of time. It was miss information of people who don’t care, don’t read and don’t listen and unfortunately that is their job. Not happy at all

The crew was amazing. The best in the last times. Great group of people.

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

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

The flight was delayed. The staff made us wait in the room that is too small and it was crowded and with no seats available for waiting. They did not tell us why the delay occurred.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

2 parts to the journey. First leg covered in a newer plane with decent staff + POOR FOOD QUALITY but the second half didn’t leave a positive impression at all as the plane itself was an older built and the crew didn’t serve properly. Language is an issue with China Eastern flights as always, but unmotivated crew just makes it even bad.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.
