Airline reviews

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

Leg room wasn't that great. Other than that it was a good flight

Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

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.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

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

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

It’s a business class ticket but they didn’t give a lounge access

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, staff and boarding were all seamless and no issues, thank you!

Poor boarding with incorrect gate numbers. Poor service they told me to throw away brand new water bottles. Poor immigration officers most likely American who hates Muslims. Poor service in the plane with no Urdu language sign posted anywhere. Horrible seats with no comfort at all they think people traveling in economy are animals. Slow food and water services. Slow baggage arrival.

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

Good. No issues except a slight delay. Crew came in late.

Not a pleasant experience, service was poor. Didn't like it

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight cancellations, delays, mass confusion and disorganization! That’s Air Canada for you, nothing new. I would have chosen a different airline if it were an option, and Air Canada continues to prove they don’t care about their customers.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

The flight from SFO to YVR was delayed and my bag did not make it to my next flight from YVR to SYD. It took almost 3 days after I landed to get my bag and when I got it, it was filled with dust

Our biggest complaint about Air Canada is that if you don’t like your seat during check-in, there’s a fee to move elsewhere. On our flight from YUL to FFL, we were charged to change seats—just regular seats. What’s maddening is that the plane wasn’t even full; there were even a few people sleeping in the middle row sections (entire rows, completely empty), using them as beds. In my opinion, charging passengers for seat changes is a cash grab by Air Canada. They are definitely not the airline they were back in the day. I suppose they need to gouge the consumer now that they pay their attendants while on ground. One out of 10.

Nothing specific. Cabin temperature was too high for some reason.

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.
