I lost my lock from my luggage, I don’t know someone took something from my bag.

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.

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.

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.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

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.

I like the boarding on time , I like the respect from the male flight attendant but the female attendant could be better. Didn’t like the food

Very good and good customer service and seats very comfortable

Short handed at the check in counter. There was only one person and so many people waiting

Plane is old and dirty. My recliner wasn’t working and I was in business class. And my entertainment kept freezing up Plane needs serviced and better maintained. And you may need to teach the crew a little customer service.

Staff were rude! Chairs are incredibly small! Comfort was minimal and food wasn’t edible.

It was a very stressful trip for me and my husband, main reason for the discomfort, kids behind our seat kept kicking the seat behind , screaming all the time of the flight , the seat in front of us has a kid with autism and a young sister with the dad , a nonstop all the 12h hours flight screening jumping overhead, stuff in his hand almost dropped on us and we have to be on alert for any move, I do understand that there will be kids but the thing is no one of the staff even bother to came near the seat and find solution , I believe there has to be a way to seat family with kids ,I’m a person who travel long distance almost every year and I used to take mostly air Canada, Lufthansa,British airways. I figured to use Royal Jordanian this time but it looks it wasn’t the right choice for us and I hope we don’t have to deal the same on our way back.

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
