Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

Crew on this flight was terrible. Especially one practicular female , she was harassing us and other families with children. Flight was good overall, if not her being rude and aggressive

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Choice of Vegetarian Food in Economy class needs overhaul improvement

The food could be better, the beef was quite tough. The crew were friendly and helpful on this flight, which has not being my experience on other Ethiopian flights.

The flight was one hour late. The food is mediocre and the screen was broken

Luggage delayed for one day. I called customer service, and they had no info and no empathy. Boarding was very disorganized and chaotic. We went nearly 7 hours with no food or snacks on the flight. This is not an airline that has respect for its passengers.

it was a nice tripe but they need to work on the serving of soda,they should be abled to serve cain soda not on cup.At least each passenger should be entitled to one cain of soda not serving on cup.thanks.

On my return flight the TV did not work the entire flight! They knew it wasn’t working but they let me sit there. The guy sitting nièce to me told me he was ok the previous flight and it wasn’t working. This is business class by the way!

The food really sucks And they really need to work on entertainment The movie selection is herendous .

Entertainment system poor - couldn't hear, no flight info etc.

I've never been served three bread courses in a single meal before. Was really impressed by the novelty of that.

Was so glad the the captain kept the air. It’s usually suffocating in there.

I missed my connecting flight due to long lines at security and immigration. Need improvements

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

I like the frequent mails we get when there is an update. Please keep it up

in the front - higher class of business - sitting in the same seat (with one empty in the middle) is not acceptable any more. need the business class to be as we paid for.

More than one hour detail with no explanation and no compensation

my husband's monitor did not work. there was a visibly ill family in my husband's row.

There was a two hour delay because of incompetence in scheduling fuel truck. Further, upon arrival in Roanoke, hand baggage was sent to baggage claim. We carry hand baggage because it contains valuable or sensitive materials that we do not want going through the baggage system. This is very poor and United needs to perform better.

Pros: "thanks to the paid upgrading we got 2 seats in the front of the cabin (row 5)"
Cons: "there was NO organisation at all during boarding: the people just stood in line, not respecting 1,5m. Also at the airport security waiting lines no attention to social distancing was respected. At arrival the off-boarding was in groups of 8th rows, not really helpfull either. A big disappointment versus the flight we had from BXL to PORTO !"

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

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.

The service was terrible. We weren’t allowed to take water on the flight and the drinks were offered only at the end of the meal. When we used the button to call the flight attendants, they never showed up and when my daughter’s drink was spilled due to turbulences, she asked for something to clean her pants at least 4 times and eventually they gave her a tissue. The flight attendants were rude and overall the flight was terrible!

I spent 4 hours untill get my bags no food no entertainment on the flight

Old planes that are not being maintained with at least basic cleaning. Plane smells awful, bathrooms not cleaned either. Very uncomfortable chair. Customer service probably one of the worst I have experienced. The AC dis not work, kept us on the plane for over an hour with no water and air condition

I lost my connection flight from Casablanca to Marrakech because we arrived late to Casablanca. I had to rent a car to continue my trip . I need refunds

Bad service in la RAM from beginning to end. The crew ladies are impolite and rude and insensitive to passengers requests. I do not recommend traveling with Royal Air Maroc (La RAM) - worst service.

Pros: "Nothing to like aboie this flight , my worst night mare . They are all corrupted I was told to pay for the trip I already paid for. The plain had an engine failure, I could not reach Casablanca for my next flight"
Cons: "Refund!!!!"
Pros: "I liked nothing about this airline. Lucky I am life… Just when we took off , the pilot announced an engine failure, we returned to Marrakech airport waiting for information instead we were walked around the another from gate to gate, yet still no information. At 3:30 PM we were told that there is no flight that day. They put us in hotel at 8:30 PM. I am at the hotel at this time without information regarding the next flight . This is the worst airline I ever used in my life, not even some sort of customer service."
Cons: "Expel ROYAL AIR MAROC from your list of offers Punish them for treating travelers like garbage. I expect a refund from the price I paid"
Pros: "The attendants were much more helpful than my last trip. Everything went well."
Cons: "I thought it was too crowded during the pandemic. Too many people on the flight. One man behind me kept sneezing so that was concerning. No other complaints for this trip but most of my previous trips were close to terrible. Thanks for improving your service."
