Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

The crew was courteous and efficient. There was no entertainment or liquor service on this short international flight.

They have misplaced my one checked bag which I have not received in Philadelphia and have lodged complaint with American Airlines, the staff of Indigo was rude with us, at the checking counter, I think she purposely withheld my one of the checked bag, because the American Airlines staff told me that bag was not received at Doha airport. Kindly help me with one of my checked bag to get it. My flight was from Mumbai to Doha and then Doha to Philadelphia.

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

There was not enough staff during boarding which had created big problems . Another thing once you enter gate area there’s no way to use bathroom and you have to be in that area 2 hours before boarding which is too much.

Boarding process was terrible. Will not travel Qatar Airways if I had an alternative. The food was one of the worst, even for airline food.

Terrible airlines - suffered entire flight due to food poisoning from stale food

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

I do not read or speak in Spanish. Only English. When asking for help, the people spoke quickly in English and pointed a lot. I wish they would’ve spoken a little slower for me to understand. There was much confusion and hurried in their message and I was unclear as to where to go

Everything was as you would expect in coach - fine. Flight was close to on time.

It was confusing because I got a notification that my gate was changed when in reality it wasn’t

Not very good, they nickel & dime you for better seats & pay extra for the checking in bag, bad service all the way around

It was a good experience, the flight was a little too long & the food was ok

Hostile flight attendants. Second flight with Jose so much better. Arrived 1/2 hour early. Thanks.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..

As usual, LATAM tried to rip me off as a Gringo. They ignored the fact that having paid for my assigned seats, I was entitled to one free luggage per person, up to 10kg, and tried to charge me USD40 per item. While they ripped me off by $160 on my outbound flight (4 luggage pieces, which should have been free), I vehemently protested this time around. Note that they only request this from gringos, not from Spanish speakers. LATAM behaves like a racist extortion organization.

Very courteous crew, the food was good and the flight was on time.

This airline is full of junk fees. After paying to get my kids to sit with me, we were asked at the gate to check in our roller bags and pay $40 for each one. Peruvian passengers all took their roller bag in the plane. I don’t appreciate airlines who spot the gringos to tax them more.

Too many fees (but that seems to apply to all airlines nowadays)

Ok, but comfort was lacking as the seats were way to small

For a 22 minute flight all you expect is for it to be safe and comfortable

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

The original seat on the flight Toronto Newark had the floor flooded with coffee spilled, so they changed our seat to premium economy. For the flight from Newark to San Salvador we were i the last row, no reclinable seats and beside the toilet. I asked for headsets to the waitress and she gave it to.me test of all the passengers, while she was staying right behind me..

Again a nearly five hour flight and pretzels is all the food you get and all you can drink water. No electric plugs in economy. Staff was totally not caring. Delta next time

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

Check in and boarding were very easy. Quite good food and a complimentary glass of wine with dinner. The acoustics on the TV difficult at times, and the options extensive though not very updated.

Because I can’t stand very long in one place, I was allowed to reword.

It was a good flight. Of course it was full, but it went well.

My baggage went to Dallas and not to Philadelphia. Do I need to add anything else?

The male steward shoved me hard when i sleeping on the isle, woke me up the only way incan descripe it was Violently. I wanted to cause a scene but was able to putnmy anger innch check, i want complain to AA

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

Everything was very good EXCEPT the food, on a five and a half hour trip. They only gave to us was snacks in first class. They didn't give us pillows or blankets.

Horrible! Got stuck in Jackson Hole and the plane kept delaying every 30 min until they finally cancelled the flight. Other airlines were busy flying out and American had cancelled. Horrible experience, we had to switch to United to get out of there!

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

The flight from Guadalajara to Dallas had mechanical issues, and was delayed every half hour for 4 hours until we were told to rebook. As it was during the busy holiday break, most flights were fully booked and travel that day was unavailable. The only saving grace for American Airlines was their ticketing staff that maintained their composure and did their best to accommodate all the disappointed and frustrated passengers.

Some of the crew members were rude for no good reason

Due to a strike taking place with the airline, it negatively impacted my flight in multiple ways. My flight was delayed over 2 hours and the food served was mediocre at best.

It was great to check carryon luggage at no charge when there was no room for ours. A hidden benefit of having low-tier tickets. Also great to stay off plane as long as possible. Airline gave us seats we wanted on this last leg, again at no charge.

Seats could be more comfortable and food can be better and price was too high

Bye portaction for cancelation , when you want to change date, you have to cancel And pay 20% as cancelation. To lose as cancelation!!! Upsell airline!!!!!!!!!!!

I got hurt and needed a wheelchair. They were excellent. I also appreciated the fact that they kept me informed thru out the whole trip regarding boarding, gate changes and luggage info.

I got hurt and needed a wheelchair. They were excellent.

I supposed to have a wheel chair waiting to take me to the luggage carousel. Didn’t happen so I had to walk up the walkway with my cane. I lost my balance and broke my little toe on my right foot, which means that I’m hobbling around with a very painful left leg and a very painful toe on my right foot. It was a nightmare.

No food. No Bluetooth for entertainment. Crying babies thought the cabin instead of placing them in the corners.

It was a refreshing experience from the past few times I have travelled with Air Canada.

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not
