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.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

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.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Good check in process Poor information on payments at Lima airport

Apart of Sky miles delta. And they go everywhere in Brazil

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

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

Really good food and service. Qatar Airways is again and again provided an exceptional experience.

Qatar was pretty OK for their services but Arangrant was awful at theirs and frankly lied to me. Qatar offers four business class fares and only three of them allow lounge access. This is a horrible policy when you pay so much for business class and shame on them for denying the simple use of their lounges for this confusion. When I requested my business class ticket with Arangrant I knew this and specifically told them I would only purchase the lowest class business seat that would still permit me lounge access on all legs of my trip. They lied to me and said I did and then I was refused this service on my return flights. I had no less than 4-8 schedule changes and got screwed by a late departure from DCA on my double connection to JNB. I lost nearly a full day on my outbound and then had little to no use of the lounges on my outbound flights. To then be denied access on my return flights made the 27 hour trip home pretty awful. Kayak should no longer work with Arangrant as they are dishonest and liars. Qatar should price all four of their business class fares to include lounge access and stop the insanity they have forced on people. My return trip home nearly ruined my entire trip to South Africa and I blame Arangrant for telling me lies and for Qatar for offering insane rules and regulations on such expensive business class fares. For the money I paid to Qatar, I did not receive the full services I was promised. I will probably never use Arangrant and their ignorant services ever again. I will question whether I ever fly on Qatar Airways again as well. When you pay so much and get such little in return, it leaves a bad taste in your mouth. Arangrant gives the whole industry a bad name and Qatar is not far behind them. I can honestly say that the wretched service and way I was treated by both have soured me on travel companies and airlines. It is bad enough that we have an idiot, felon, racist and bigoted president and administration to contend with while he has started an illegal war, I did not expect to get screwed over by Arangrant and Qatar as well. Shame on all of you.

Very poor No information given to why we turned around.. No one at airport to help

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

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

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

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!

I had the best flight crew I have ever experienced in all my years flying with AA. I would specially like to thank Till Tatum/96038 for her kindness professionalism and outstanding service! My son turned 8 years old one day before our flight and she went out of her way to make him feel so special. We will never forget this flight! The whole crew made a special card for Frankie’s bday and it really touched our hearts. He will never forget it and neither will we! Thank you with all our hearts! We hope to be on more flights with Till Tatum and this amazing crew.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

The plane was comfortable but the crew wasn’t friendly.

I was traveling alone abroad for the first time and the staff was not helpful and rude at times.

Overall fine. Seemed like one of the older model planes? Crew was mostly very kind, though some of the female attendants were a rather abrupt during the food service.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

On time departure and early arrival. Flight attendant very nice.

The "on the ground" A/C was not working. It was so hot while waiting to get in the air, a passenger from the rear of the plan declared "I just can't!" and waited in the gangway until time to close the doors. It was miserable. But the crew were champs and had an amazing attitude. I know they were as miserable as we were but didn't let that affect their performance.

Delayed 24 hours. Should have called it much earlier They provided quality accommodations, food vouchers etc. FINALLY The issues started at 8 AM and they cancelled the flight at 11:30 PM, with no plans for a new flight.
