I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

It was very good and it was not my first time I always take Turkish air line for my travels

Food excellent Bathrooms improve cleanliness needed Staff fairly well attentive Entertainment fair Seats lie flat worked well

Check in was not available online. It was super long line to check in

I did not have a good experience from the first point of contact to the check in person to boarding and the comfort of the seats. I would not travel on Turkish again. I will let my family and friends know about my experience which was not a pleasant one.

My flight was cancelled with no warning! I had to find out right at the airport when I arrived from my previous flight!

Excellent service. Made United 's business class look like a cattle car

I have been flying Turkish Airlines for the last 5 years it’s always great service, on time , excellent food, only one thing wasn’t reliable is their on board WiFi most of the time it doesn’t work.

My checked bag did not get loaded on the aircraft in Istanbul. Other than that, the flight was smooth, on time and the crew was friendly, efficient, and professional.

You need to weight all bags together because we were 2 and we allowed 4 bags plus hand carry and personal items. We trying to saved bag like we put our stuff in 3 bags so we don’t have to carry more bags and airline also save space time less bags less work. We had only 1.6 kg over and we requested crew he said it’s airline policy that you need separate bag that’s ruined our mod and carry that suit in our hand in plastic bag he didn’t understand that we have less bags that make sense if we brought over luggage then it’s problem. I think if you guys change your policy and weight all together that will be good

Better than other airlines but still not at the top with other airlines that you pay the same price and services and customer service are much more well performed with care and attention to the customer. Still a long way to go. Some of the flight attendants are speaking English like they translate direct from Turkish. They need to improve the customer service for a global travel.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

United ground crew and pilots are friendly. The in-flight staff (flight attendants) are the worst in the world. Multiple trips, always unpleasant, combative, use implicit threats to not allow for a discussion on their decision. Authoritarian. This seems to stem from an internal corporate wide policy as I doubt that United is intentionally searching for people that are not fit for customer facing positions. I will not fly United again. Good luck fixing your business

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

Check in process is terrible, only one counter opens to serve over hundred passengers, agents are incompetent and took too long to get passengers boarding passes. Supervisor is no help neither. On board entertainment 90% monitors were defective.

Check-in could have been a little early and I wished the airline would have serve some better real food rather than serving a very hard bread for a 8hrs flight.

Long delayed that cause missing my connection. Accommodation and food at the Casablanca airport was horrible

Educate your crew members they need to understand what their job is and customers service and be human.

Comfort and organisational prowess of the entire crew. Baggage handling can be better. No had all my luggages after 6days of the flight.

This was the worst experience ever. It was such chaos at boarding due to boarding zone and letting everyone with children and strollers go first. Once the plane door closed they didn’t let us know why we were not moving until after 30 mins of sitting on the plane. Then ANOTHER 2 hours passed with no other communication or update as to why we were still sitting on the plane. 2 and half hours of sitting on a plane! When I ask a flight attendant what was the delay he gave ALOT of attitude and said he don’t know what’s going on. This flight attendant was soooo rude to customers to the point one lady was telling him how rude he was. I also felt other flight attendants spoke to the people who spoke their language; I am an American so this was also upsetting. The food was horrible, I only ate the bread. We finally landed and we almost missed our connecting flight. We was able to run and make out next flight within 30 mins. Our flight from Casablanca to Marrakech was quick. BUT here is where I was really UPSET. They left everyone luggage who was on the flight in Casablanca. We went to baggage claim and they had Attitudes! How are you mad with us for losing our bags, I don’t get it. We had to wait for the next flight to come in with our bags. The baggage claim guy said they wouldn’t deliver our bags to our hotel because of past experiences; now we have to pay for another cab to come back! They had so much luggage outside of baggage claim I can see this was happening to a lot of people. They said they would email us once our bags arrived. He told us the next flights coming in (which I researched myself and he gave the wrong times!). We took a cab to our hotel to wait. I seen my bag was at RAK airport (because of my AirTag) 4 hours later but no email from baggage claim. I waited two more hours and still no email letting us know it arrive! We missed dinner plans! We went to airport and got our bags (security at RAK was rude to us and had us walking all around in order to get to baggage claim). I will NEVER fly with Royal Air Maroc ever in life, even if it means I can’t fly to other countries that I would love to visit since this ruined my friends birthday already. I PRAY our flight back home is wayyy better. This is no way to treat people. I fly frequently so I know how airlines should treat people and Royal does not!

On line check was unavailable even tho I was receiving emails to check in and select my seat. At the gate was told all seats were taken ahead of time and was pre assigned a bad seat. When could you check in the choose a seat ???? The ran out of all food choices in business class !!! I had nothing to eat. They told me to pre order a special meal. I don’t want a special meal I was a regular meal. Seats very uncomfortable for business class prices.

Babies, crying, movies and sound doesn’t working overpacked and delayed flight

Pretty good flights! If they can let y u s know regarding delays by announcing it in the PA system it would be a good business practice!

While I had a business class ticket I wasn’t given priority to boar. Again my luggage had priority tags and these bags didn’t come out till the end!! The food at the lounge was only two type of sandwiches and warm juices and soft drinks I thought I’m paying for good services but the least u can say it’s mediocre at best. I’m considering not to use TAM AGAIN.
