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.

It was pretty good overall. I just wish the crew didn't have to interrupt you every five seconds to ask you if you wanted anything, I mean that's what the help button is for. When someone is tired and sleepy and still getting their bearings, turning on DND button is maybe not the first thing on their mind.

Food and entertainment was very very bad. Also, Doha airport is very bad. Entertainment was same for last 1 month....no change. Old movies. Food quality was sub par.

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

Food and Service inside the flight. Airport service from Qatar is not good mainly because of lack of coordination and not used of seeing so many ppl commuting

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

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.

Fine. Don’t think I would fly with them again

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.

There was no phone charger, uncomfortable seats, unprofessional flight attendants, didn’t like food. Could not reserve seat in advance

I missed my plane because there was a lot of people during the migration process. The airline has the chance to care for their clients and they could get the passengers missing in the flight. I lost a day of work and Montfort transportation to go back home and go to the airport again. Unfortunately the airline doesn’t care about that. I use latam at least 4 times a year, so I guess I need to be treat better. In addition, one on my baggages didyarricw to my destination. So frustrated with this trip.

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

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

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 from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

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..

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.

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

Our yoga retreat was cancelled and besides not refunding is, they would not even let us change dates or locations. As a matter of fact they wouldn’t even talk to us and kept referring to the travel agent, who said they couldn’t change anything and it was up to the airline to do so. They passed the buck until it was too late to do anything about it. Avoid Latham and Budget Air for your travel plans.

Pros: "The seat was comfort, good attention, flight on timing 😇"
Cons: "In several times the plane went down and up, and I think the pilot had no experience or it was the first time flying"

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

The best part was we weren’t too delayed. Seating space in economy is insulting and about as uncomfortable as one could expect before mutiny breaks out. Prep for landing happened well over 45 minutes before wheels down: no final garbage pickup and it interrupted those of us who needed tray tables down for dinner, etc.

Did not like the seat spacing. The seat was very narrow and tight.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

I was very fortunate it was not a full flight , so I had 3 seats to myself. Absolute bliss. Food very good. Except dinner desert was a sugar bomb. Can you provide yoghurt or some healthier dinner desert. Thankyou

Crew was wonderful and attentive. Chris (I think that was his name as I was seated in the back in 52F) was amazing and funny. The captain was informative and did everything to get us to Denver as close to on time as possible. Bags came quickly at baggage claim. Online check in would not allow me to change my seat 24 hours ahead of time with dozens of seats showing open and I really do not enjoy being in the back of the plane for long international flights.

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.

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

I like the food, the entertainment, just more room on the plane

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

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.

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.

Very disappointed with the crew and the lack of attention given to the passengers. On a 5 hour flight they never offered a snack. One time offered a beverage and didn’t pick up the used cups until the flight was on final approach. The two flight attendants in our section mentioned that they were best friends and compared their pre flight shoes. When paying for first/business class there is a level of service that should be expected. These two spent the majority of the flight in their seats playing on their phones and laughing with each other. Very frustrating!!!

Food was terrible. Flight attendants OK. Only saw them at food service. Other than that they paid no attention to the passengers at all.

Gate change was a little tough but it was a good flight otherwise

Flight was a delayed a few minutes but nothing crazy, everything went extremely well

Our seats were better than i had anticipated. They provided nice pillows and blankets as well as a kit with ear plugs, sleep mask and headphones which made the long haul flight better. Their food selection and service was good. I appreciated that they came through the cabin with water a few times. We were ahead of schedule which was nice!

I could not take my trip because both of my cruises were cancelled. Kayak said it could not credit me for the flights. This is the last time I’ll use Kayak

The service was good during the flight, but booking process was arduous due to mysterious partial cancellation (on the return leg), which took me 1 whole day to connect to the RJ’s NYC ticketing department to straighten it out. The reservation line of RJ customer service said they did not have the authority to un-cancel it, nor refund the ticket. To undo, I would have to email the NYC office and wait 5-6 days for reply, while my departure is 5 days away. Then the NYC phone number given (and I also found on their website) had no one answering, until I got someone in accounting or HR department to transfer me to ticketing dept. Then the seat upgrade at the gate only takes cash, no CC. From speaking with other tour mates, other airlines were given them the similar headache too - cancelling part of the trip without rescheduling options.

Air Canada ignores economy passengers. At Narita airport, 6 ground crew members were catering to priority passengers in Area A, while no service was provided to the economy passengers at Area D. Over a hundred passengers were queued up at Area D, but no ground member came over to provide any directions. The self-help check-in system was malfunctioning, rejecting our luggage that weighted around 12kg as oversized. Hence the hundred or so economy passengers were really angry about the lack of support at Area D.

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.

On time, easy with no issues. Arrived 15 minutes earlier too.

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

Air Canada switched my connecting flight to Alaska airlines without any communication to me. The process of finding this out, needing to leave one portion of the airport for the next and what i should have done with my luggage was not communicated to me at all. Even the Air Canada agent that noticed the airline switch at the terminal did not explain this process to me. In doing so my luggage did not arrive with me. The delay to create a claim too 2 hours.

Food was great. Staff was great. I would have liked to see more in flight shopping - they went by so fast I missed it. I would have liked more variety in tv shows but overall flight was great. The staff made all the difference.

I've traveled AC many times in N.A., though only 2 other times to Europe. It appeared to be a new aircraft, the Economy seats were slightly wider, good legroom and reclined well, however the ergonomics were poor compared to their previous generation aircraft. Reclining to sleep is very uncomfortable as front edge of the seat is pronounced and cuts into the circulation of the lower legs; unfortunately this typically occurs with someone shorter than 5'-6". I'm 6'-0" and have long legs, so if its uncomfortable for me then it will be for most people. The overpronounced seat causes misalignment with the lumbar support, making it impossible to be comfortable to attempt sleep. Seat is only comfortable in the fully upright position with feet flat on the floor.

The bathroom I used could have been cleaner and tidier. Didn't look like it was kept very well. The staff were super helpful. There was an issue with my screen, and they rebooted it for me. They were also great at dishing out our meals, and cleaning up after.
