We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

We booked with Qantas instead of Delta and we instead flew on American Airlines. American is not our favorite to go on. No leg room and the width of seats are a joke. Your are packed like sardines on American flights.

My experience was great overall. Tanya was particularly friendly and helpful the entire trip. I was very pleased with her customer service skills. The plane was an older aircraft but the entire way was comfortable with barely any turbulence at all. Qantas should speed up its fleet renovation. Totally recommend using this airline.

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Qantas is always subpar beyond comfy chairs for a domestic flight

an hour late, then had to disembark on back stairs and take 4 flights up to get to main airport. No warning, and difficulty for those with canes and poor knees.

Flight arrived late with no one to help over 30 people rebook. I slept at the airport.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

It was a good flight and no complaints. It just wasn't anything that was better than any other flight.

The crew were wonderful - if only the customers were as well behaved as the attendants!! Ha ha! If you could just talk to God and ask for less turbulence next time.... Juuuuust kidding....

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

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.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

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 was very good. It was a long flight and being a tight with little leg room.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

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

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