Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

Very bad groud crew taking bags less than 7kg Bad food Old plane

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

The flight was fine. There were a lot of babies and toddlers that did not do well on a 12pm flight that lasted for 13 hours. Some were awake and cranky all through nap time and bed time. I don’t understand why Royal Jordanian does not have WiFi on its planes, even for a fee.

Not reserving the bassinet seats for babies who need it. Baggage allowance isn't good. Food quality very poor.

Not so good. Within 24hrs of departure, I checked the seat map and 6E, 6F were available. So i selected them. After reaching the airport, the staff said that those seats were taken away by someone. I told how could that be possible since the seats were taken away by me. But she insisted that someone paid for those seats. I disagreed because the seats were assigned to me. So she assigned us seats all the way down. When we boarded and plane took off, those 2 seats were vacant throughout the journey. To add salt to the wound, one of my bags went missing. I was left with only 1 pair of clothes which was in my carryon bag. After so many followup calls, my bag was returned on the 4th day. I don't recommend Royal Jordanians to anyone.

Poor job on boarding...lot of delays on the landing

Terrible. My luggage didn’t make the connection, even though we had an hour and twenty minutes. My luggage arrived in my city a day ago and I still don’t have it. I will go three days without my luggage and there is no sense of urgency to get it to me.

Two hours late getting in with no apparent reason for repeated delays.

Still old cabins They have to know how to do with loyal members

Very poor we had bad service in our first flight our flight was delayed 3 times and waited 12 hours in the airport till they finally canceled the flight giving us no reason then had to get a hotel in newyork and depart the next day on the same plane that we had boarded the day before and was dirty from us boarding and un boarding it was the worse experience!!

RJ is very good and nice don’t have luxuries flights but the staff are so helpful in YYL or AMM and their office at 7th circle are amazing

No Wi-Fi 50% of headphones handed out do not work. Otherwise pleasant.
