Airline reviews

LATAM clearly does not have well-established policies re: luggage for international flights to Lima followed by domestic flights within Peru (in my case, from Lima to Cuzco). On the way in, they forced me to pay $50 in Lima to check my second carry on bag (the three bags were included in the fare from JFK to Lima). On the return trip, they told me at check in that I would have to pay $50 again at the gate (she said they couldn't accept the money at check in) Then, at the gate, they initially told me I would have to pay several hundred dollars to check the big bag through to JFK. I protested, and showed them a print out of an email saying the checked bag was included between LIM and JFK. Than a second woman showed up, and told me I wouldn't have to pay anything at all -- which was great news, of course -- but that means I was incorrectly charged the extra $50 on the incoming flight. Basically, just a mess. Also, their website is completely non-functional -- it was very cleear that all the airport staff knew the website was nonfunctional, too.

We liked the way we were treated by the sraff at lima airport counter and the the flight attendants. We did not like the fact that the kiosks at airport rebooted after we entered our information and then told us that there was an issueand we needed to go to the counter. Such a waste of time for a group of 6. Once we got our boarding passes there was no assigned gate so we did not know where to go.

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

Good check in process Poor information on payments at Lima airport

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

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

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.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

This was my first time ever flying China Eatern and it will not be my last. I was very satisfied with my whole experience and trip. Thank you very much and until soon.

It was just fine. The sirlines did live up fully to my expectation.

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.

While boarding at PVG, there was a ticket checking at the gate, then there was another ticket checking at the bottom of the escalator, which created quite a dangerous congestion. Not sure which idiot made this absolutely unnecessary arrangement.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Plane was good. But food was bad and air host was so rude. I will never fly with China Eastern again

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

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.
