Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

It took so long to do a baggage drop and it was bad enough. I had to go to the extreme end of the terminal because it’s a USA flight and go all the way back to the center indigo to security.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

Every flight was delayed except the last one. One layover turned into two. Travel time extended by three hours. No compensation offered. Repeatedly asked if I'd like to cancel my flight for a partial refund.

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
