Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

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.

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

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

Initial booking was confusing and had to get new CC issued.

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

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 baggage is lost. Flight cancelled, Rebooked ticket through long routes. Mental stress, emotional hurt

The flight crew where really good. Better then the crew from BNE to SFO

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Pushed back only to get deplaned due to a tire damaged by ground crew. They did at least go pretty fast. The bathrooms should be banned under the Geneva convention. No room to even sit straight on the toilet. The under-seat entertainment units block what little leg room there is.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

The food is terrible. The same pasta or chicken with bad taste and presentation

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

I think we deserve more than 25% refund for losing first class seats when having to reschedule flight due to weather.

Qatar airways ,boarding arrangements at Hamid international airport could been better

I love American. I’ll never fly anyone else if I can help it.

Tell the crew (when boarding) to yell at the imbeciles blocking us from walking up to scan. I promise everyone crowds around and half of us (most the time I’m group 4) have to push our way through. Your staff is awesome, the public - not so much-

It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.

Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?

Not great. Booked Extra seats and got nothing extra at all. It’s basically a big budget airline.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

I have a gluten allergy so did have any food

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

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

It was a smooth flight both in the sky and landing!

I knew I was going to fall asleep unsettlingly from exhaustion so I warned the guy next to me in advance. The attendant took to checking on me frequently and even insisted I take my snack because I said no while sleep hazed and then absolutely wanted it about 5 minutes later. He was So caring and kind to my situation!!

The flight attendants were not very nice. No smiles On my return trip I was charged for one bag $83.30 although I had purchased the flight including one piece of luggage. Can this be refunded to me? Thank you!

Good. Need more flights going to Barbados because we had a very long layover. The food was as expected of airline food but still can be improved. I had a seat at the back on one of the flights and by the time the foodcart arrived the only option was the vegetarian alternative. This could be improved on.

It was good except I was sitting beside a bigger gentleman so I didn’t have much room

Bad experience boarding and flight got delayed didn’t make it to my next flight

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

Previous flight from Melbourne to Brisbane was late. I had 1 hr 40 min to get to the connecting flight. That was not enough time as I had to take a shuttle bus to change terminal. Then needed to get through security and customs. The airline was announcing my name to board at 9:10. The take off time was scheduled for 9:40 but I was again one of the last to board at about 9:20. Kayak needs to allow more time for these connections

Almost missed boarding, mass line up made me be the last person. Wish the announcement was more loud, didn’t hear what seats or zones were ready. Being last also made finding space for my roller bag. Fortunately the flight attendants made it work!
