Pros: "The movies"
Cons: "Lack of crying babies and lack of sleep seats too close lack of comfort"

Pros: "The crews are always awesome. The food great especially since they always have cherry juice, my favorite!"
Cons: "The flight was delayed, and then seemed rushed at call Last Call. Also the ear phone jack was a double that even the TA ones didn't quite fit. Glad it was an overnight flight and slept most of the way."

Pros: "NOTHING"
Cons: "No options to change booking and the one given was absorbant pricing"

Pros: "Flight was cancelled"

Pros: "the crew was good. The seat were not comfortable"
Cons: "food could have been tastier"

Pros: "I was feeling very bad during flight. Crew made everything possible to make this flight comfortable for me. They took good care of me and were stopping by me, to check how am I feeling during whole flight."
Cons: "This is not about airlines, but about passengers. All airlines should prohibit passengers to use fragrance. This lady who flew next to me, had strong perfume and it felt like she used half of the bottle, cause it was impossible to breath."

Pros: "The food was great, customer service also good and price is Afordable"

Pros: "Lots of entertainment on the plane. Very clean. I like the personal touch of a travel Bag given and large head phones."

Pros: "I was impressed by how Turkish Air treated me when I missed my connecting flight in Istanbul It was confusing to say the least but once I got to the right location they could not have been any friendlier, kinder, or gracious My hats off to Turkish Air THANK YOU"
Cons: "It was a tight space and they kept giving me things (pillow,blanket, slippers and socks, and headphones) that I didn’t need or have room for I appreciate the thought Return trip I’ll be more aware and decline what I don’t need"

Pros: "The recline and comfort of the seat is good, and the map and entertainment system is OK."
Cons: "The flight was delayed, then we sat in the airplane for an hour before we took off, with kids screaming and the cabin at seemingly sauna temperatures. Once we took off, drinks weren't even served until 2 hours after take-off (for a scheduled 6:15pm departure - actual was more like 7:45pm). Maybe it was due to some light turbulence along the way or something, but they should tell people that is the problem and the reason they are not serving food and drinks, if that is the case."

Cons: "A 30 mins delay"

Pros: "The flight was quite good, with pretty tasty food, plenty of food and drinks, chairs reclined quite a bit, little extra and gifts for kids, slippers, socks, ear plugs."
Cons: "Boarding prices very disorganized. No announcements and a crowd sprig where everyone just pulled at the gate. Very few announcements in general."

Pros: "Comfortable, on time and as always good service from Turkish Airlines"

Cons: "They took over 6 hours to decide if the missed and overbooked flight would be free or an additional $1000 (which they originally demanded). Spent over 30 hours in the airport with no help from the airline - NEVER AGAIN"

Cons: "Delay around three quarter an hour."

Pros: "See previous"
Cons: "See previous"

Pros: "Leg room is better than any other airline"

Cons: "They was late for boarding The food is bad It's was my bad experience this travel"

Cons: "Trying to reclaim our laptops at the end of the trip was a nightmare. They confiscated all electronic devices larger than a cellphone due to new Trump regulations (not their fault). Fine. But they were so disorganized about the process. When trying to reclaim the devices after the flight utter chaos ensued. That was their fault. Passengers were on the verge of violence and it could have been avoided by simply being more organized."

Pros: "I had a most pleasant experience flying from New York, NY to Kiev, Ukraine. Everything about the service was just right. Thank you for your kindness and attention to detail. From now on I will only fly Turkish Airlines when going to Kiev."
Cons: "Nothing."

Cons: "The international transfer line in Istanbul was an absolute nightmare. I had to jump to the front of the line or I would have missed my connection despite having a 90 minute window of time to make it through. It seems this airport lacks the capacity needed to get people through efficiently based on the numbers of travelers using it."

Pros: "Flight delayed 11.5 hours...not their fault, but there was no communication from Turkish Airlines as to what was happening."

Pros: "Overall smooth flight. Arrived time at Atarurk airport and well managed by flight crew and ground staff."
Cons: "They forgot to invite passengers with small children to board first. In flight service was good but seemed to be a bit slow as there was only one flight attendant serving half the economy cabin. They used to do a second drink service on this flight which was really nice before. Food was ok but TK has had better food on my other flights. The meatballs aren't as good as some of their more flavourful suppers."

Pros: "The crew is very attentive, although at times lacks some foresight in dealing with passengers. The aircraft was quite new and clean. The entertainment system was outstanding and the food good, although a downgrade from THY experiences from a few years ago."
Cons: "The passengers on some Turkey--US flights are hilariously terrible. People getting up during landing, littering in the plane, clogging toilets, creating spills, NEVER listening to announcements made by the crew, etc. It's essentially a zoo. I sat by a bulkhead seat, and I had maybe 200 people push by my feet, step on them, knock around my shoes and TV console during the flight. It's a somewhat tiring spectacle for 10 hours on end."

Pros: "Great crew, pleasant fligt"

Cons: "Everything was fine."

Cons: "Staff on Istanbul airport is rude. They don't respond to people"

Cons: "Nothing negative"

Cons: "The WiFi"

Cons: "The ticketing counter gave very bad guidance for when I arrived, thus refusing to allow me to check my bag. And insisting that I had to cancel my skymiles ticket and purchasing a new ticket. Show up at least 2 hours before at DCA for intl flights, employee incompetence could cost you $$$$"

Pros: "The service on plane was great and so was the opportunity to check luggage, although I was happy I didn't have to."
Cons: "Boarding from DTW to LAX, we had to stand for a long time on the jetway and it was really cold. It was the holding place after they checked my ticket. Otherwise, it was a great experience flying Delta."

Pros: "Boarded on time, service was pleasant."
Cons: "Departed a few minutes late due to need for mechanical attention."

Pros: "It was cancelled"

Cons: "For some reason there were 4 really young children seated all in the same area. Kids will be kids, but perhaps spreading them out wouldn’t make one particular area so loud and disturbing. Boarding the plane I a more orderly way would also help."

Cons: "Not have canceled my flight!!"

Pros: "Seat had spacious leg room entertainment was very good"

Pros: "Smooth flight. Fairly good meals. Friendly crew."

Cons: "Everything was OK"

Pros: "Staff was very pleasant , polite, and accommodating"

Pros: "Everything was fine, the crew was excellent. We liked that Lufthansa did provide the special meals (that we requested on-line) for our family."
Cons: "The boarding was rather slow (but not extremely so). Calling boarding by row ranges, like some other airlines do, may speed it up or make it more comfortable. The seats were not too comfortable, but within what one can expect for an Economy class --- and not too bad, either."

Pros: "Staff is great"
Cons: "Food is not good."

Cons: "There was an issue on the bus to take us to the teminal cuz a passenger took another's passenger's backpack which looked exactly the same but they made us wait on the bus til the mix up was settled. A lot of the passengers got frustrated cuz we had connecting flights and the workers by the plane didn't care including the bus driver. We finally went but we almost missed our flight .we had to literally run to the gate to make it."

Pros: "There were blankets and pillows for every seat. There are USB ports at each seat as well as headphone plugs."

Pros: "Flight was on time and flight crew was very good."
Cons: "The food was not very good. Leaving Germany, I expected better tasting food. Our food leaving the USA and going to Germany tasted much better."

Pros: "It's not only pilot/auto-pilot or only weather dependent for sure, but ride was extremely smooth. landing was fantastic. Entertainment options were great. Crew was friendly and attentive. Sucks for LH, but I had to one sitting next to me on the 8-hour flight! no crying babies, no snoring. yiey!"
Cons: "Maybe US is ahead, but my experience with 2 terminals at Hanover and Frankfurt was that information exchange isn't good. Gate number was available at the last hour or so, which then got changed. Not just this flight. many flocks of people were running around to find their new gate... also as I mentioned climbing several stories of stairs with carry-on isn't fun! Not on this flight, but on my initial departure from US to FRA, monitors said go to Gate B. I got in line for Gate B as there was some security check, then we were told there was another B?!@ We had to go down and take the bus for that...written.. No where!"

Cons: "The air on the plane was unable to be controlled."

Pros: "We were kept informed of prigresd"
Cons: "Delay"

Pros: "Wi-Fi and in flight entertainment"
Cons: "I'm 6'3" cramped in economy"

Pros: "Great service. Comfortable business class seats."

Pros: "Crew and service was very good,"
Cons: "Reclining seats. Great for you but not the person behind you. It puts the screen about 10 inches from your face when the person in front of you reclines and it's impossible to lean forward and rest your head on the tray."

Pros: "The crew was pleasant, bathrooms clean. Despite a late departure we arrived on time."
Cons: "It was a bit warm on both flights from DTW to FRA and the return. I usually dress for flying assuming it will be chilly but it was the opposite, a bit warm. No individual air control either. the last meal served was a ham & cheese sandwich which tasted odd..I couldn't eat it, other meals were fine."

Pros: "Lucked out. Flight was quite empty. Travel was comfortable and easy. A smooth ride all along."

Pros: "The entertainment choices were excellent and the service never stopped. The plane was comfortable and the bathroom clean. There was some turbulence, but that is not the fault of the airline, nor did it really bother me."
Cons: "There was a snarky attendant, but not all of them were that way."

Cons: "Lack of drinking water fountains at the FRA airport"

Pros: "Great crew!"
Cons: "The sound quality of the loud speakers for the announcement was awful. The sound for the movies was also not great."

Pros: "The crew was friendly."
Cons: "We were a little late with boarding. I prefer Lufthansa for travel, but I can think of a ton more, easy to serve, more healthy and delicious menu items. The food smells good, usually, but it isn't that great. The chicken I had was fine, but the side dish (sweet potatoes) wasn't good. The salad had too much radicchio, the soft cheese was too rubbery to cut (spilled my water doing so), the cake wasn't up to German reputation. Also, one flight attendant, got her own suitcase down, at least 5 times, stretching directly above me, with her jacket in my face and never apologizing. My seat wouldn't recline, nor could other peoples. This is why I paid to choose my seat, so I could sleep, more easily but I sat upright the whole time."

Pros: "The crew did a great job. The flight turned out to be nearly 10 hours since we had 150 knot headwinds. The food and free wine made things much to tolerable. You can't go wrong with Lufthansa."

Pros: "Everything was fine even though the plane was late,"

Pros: "Great Service Great Stuff will continue with LH in the future"

Cons: "Sounds in TV doesn’t work"

Pros: "Friendly crew."
Cons: "Plane was delayed almost two hours due to fog but I can't blame Lufthansa for that"

Pros: "Flight and land was smooth. I like Lufthansa, because it is safe."
Cons: "My trip was 8 hrs, we get water or juice only 5 times and very small cup 100ml, not enough"

Pros: "No vegetatarion food on return flight"
Cons: "No vegetarian food on return flight from Frankfurt"

Cons: "way too difficult to try to get exit row seats- I went on line precisely 23 hours before the fight and could not figure out the exit rows- legend said they would be marked by a red line but were not. Very frustrating."

Cons: "Canceled and delayed flights are unavoidable but deceitful customer agents is unacceptable. We will never fly Lufthansa again."

Pros: "ON TIME."

Pros: "Everything about this flight was amazing. The food was fantastic, the service was better, and my comfort was always at maximum. This company makes all American domestic companies pale in comparison."

Pros: "When my traveling companion suddenly became acutely ill the flight attendants stepped right in and assisted him to an available Business Class area where he could be cleaned up (including changing his soiled shirt to a clean one from the 1st Class supplies) and made more comfortable. They checked on him frequently during the rest of the flight and made arrangements to get us assistance off the airplane in Detroit and through the crowded airport in record time in order to get him to the ER as soon as possible. We are so grateful to them for their caring help during what could have been a very embarrassing situation."
Cons: "We had no complaints or suggestions. Flying with Lufthansa was a wonderful experience during a difficult situation."

Cons: "The head rests were very uncomfortable."

Pros: "Flight cancelled see above"

Pros: "The problem was a family with 4 children who failed to parent their children which made this 7 hour flight a nightmare. Their children yelled, screamed and cried the entire flight and their parents did nothing. Their children laid in the center aisles, jumped up and down in the seats like a trampoline. They played with the trays like a toy repeatedly opening and closing them for fun. They tossed pillows at each other and the father handed them back to them to do it again and again. The parents didn't even seat their children in - the flight attendant had to do it. In our section there was no sleeping only total frustration. I love kids but sitting behind totally irresponsible parents made this return flight a nightmare while awake"
Cons: "Flight crew inability to handle unruly passengers"

Pros: "My flight from Frankfurt to Detroit on Lufthansa was very enjoyable. The crew were great. They were very friendly and attentive to the passengers. I would choose to fly on Lufthansa again in the future."

Pros: "Staff , food , wine"
Cons: "Sat too close to the toilets , bad wafting smells. Only 1 earphone on my head set worked, unless I jiggled the plug. The plug did not fit neatly into the jack ."

Pros: "The flight was on-time and very smooth. Check-in and baggage drop were incredibly easy. I also liked the self-scanning of the boarding passes to board. Great number of options on personal entertainment screen - including movies, tv shows, and music that people actually want to listen to! Great flight overall."

Pros: "Upgraded after a terrible flight out. This was much better. The food was better. The seats reclined like normal economy seats in domestic flights. Lufthansa definitely knows how to make economy seats uncomfortable."

Pros: "Service by crew on board."
Cons: "Delay after boarding flight."

Cons: "Only the lunch wasn't good, there was only pasta at the moment"

Cons: "Friendlier crews"

Pros: "Crew were excellent"
Cons: "Old aircraft. Uncomfortable seats in economy. Entertainment screens old and almost impossible to watch - watched my iPhone! No mobile phone charger."

Pros: "Confort and kindness"
Cons: "It was too cold"

Pros: "The crew tried to be helpful but were equally frustrated with the ground crew."
Cons: "Follow your own policies. Allow people to board (economy plus) with their hand luggage who have followed all the rules and chosen a seat in the front of the plane. My daughter and my KLM approved baggage were taken by the boarding crew while allowing other passengers to go with more than allowed"

Pros: "Customer care was super supportive"
Cons: "Inflight sandwiches"

Pros: "The crew was amazing, flight on schedule and good entertainment."
Cons: "Space is just reasonable on a long flight, even if there's seats more spacious that you could choose if you pay more."

Cons: "Not being seated next to small kids. Perhaps they should have a separate section? ;-)"

Pros: "My seat"
Cons: "My suitcase wasn’t in the plane. 8 hours in the plane and no one offered us water. We had to look for flight attendant. Entertainment wasn’t great not too many choices and quality of screens was poor"

Cons: "Lost all our bags so couldn’t ski"

Pros: "Good food, friendly service"
Cons: "More trash pickup; only one round of beverage service"

Pros: "The crew were amazing and the flight was very smooth."
Cons: "Keep up the good work"

Cons: "At the check in they made me pay 50€ for my luggage. This is really upsetting because from Houston to Venice they didn't make me pay. Either the website wasn't transparent or the lady at the desk made a mistake. Very upsetting, one luggage should be included."

Pros: "And i got it 2 days later. I had to buy a lot of items which were in my suitcase The returning of the suitcase was awfull. In tge end after many phone calls I received it On the 18/12 evening, 2 days after my landing"

Pros: "Shirt flight but well catered, boarding was efficient and quick."
Cons: "Not lots of legroom but adequate for an hour long hop. It was cold on board and also had to board via steps from outside"

Cons: "That it didn’t happen."

Pros: "Friendly staff, good service and on time departure/arrival."

Pros: "Booked extra room seat which gave me good room for seating"

Pros: "Nothing"

Pros: "Friendly staff"
Cons: "Entertainment was dated and poor in function. Our bags were 99 dollars each and we’re both lost and didn’t arrive. I just filed a claim and got rude service saying I should have filed the claim at the airport baggage area but there was not anybody there to do the claim then he agent upstairs said they just spoke to them and they are there and I should have done it there. This was so rude and there is no way to get back into customs area. If we paid 200 for bags I expect them to arrive on time. I’m asking for a refund of the baggage fees."

Pros: "The aircraft was clean"
Cons: "The food was terrible, wifi was extremely expensive (Delta had free messaging over their wifi)"

Pros: "Due to lightening bolt strike our pre-Y2K era plane got switched out with a newer plane with modern media delivery at the seats."
Cons: "This caused a two hour delay in boarding and another 30 minutes on the JFK T4 tarmac. Same crappy headphones so it wasn’t the"

Pros: "I personally do not appreciate the food on this leg of the journey Food Ams to Dxb is GOOD!!"
Cons: "The snack & “ solid eggs” in breakfast. Fresh fruit was good."

Pros: "Very friendly crew"

Pros: "Only thing we liked was the fact that we were able to get onto our flight at all..."
Cons: "Was not informed that checking in online is the only way to secure a seat. So, regardless of whether you book your tickets 3 months in advance or the day before, you're not actually guaranteed a seat unless you check in online. We weren't told this until we were at the airport and checked in there that we might not be able to get our pre-booked in advance flight because of over-booking from KLM. We then had to wait and see if there were seats available when boarding. Luckily, there were, but we were not sat together. Not the greatest start to our first holiday together as a couple. We were told that if there weren't seats available, they'd pay for us to get to another airport to fly out, which would have meant a huge delay on the only time off we'd get together this year and have to rearrange our pre-booked and pre-paid living arrangements for the week. All because there wasn't a lot of emphasis on the need to check in online before hand. You'd think if someone checked in at the airport, that would be more of a guarantee that they'd be flying with you that day, but apparently not. Definitely not impressed or happy with this part of the KLM experience. This is the only company that we've had this problem with, they should make it clearer that it is essential to check in online."

Cons: "Amesterdam airport employee was really rude"

Pros: "In flight food was enjoyable"

Cons: "The Guy who had an accident when boarding causing a delay. Also I didn’t like the wait fir checking as passengers with children went before business class and should be after."

Pros: "Short-hop flight, fit for purpose."

Pros: "Thankful for coffee being served without charge. Not all airlines do that."

Cons: "Long stop over at Schiphol. Too Long!!!!"

Cons: "There weren't too many options. The movie selection was very limited and the tv show were over 20 years old in some cases"

Cons: "The fact that there are different airline carriers for one flight is hard. In my second flight they made me check a bag which was considered a carry on during my first flight"

Cons: "Flight delayed, had to take two more flights and was a four hour trip turned into a 12 hour, 4 countries trip"

Pros: "Excellent service and comfortable flight"
Cons: "Flight delay roughly an hour"

Pros: "Nothing"
Cons: "Airlines had no record of our pets flying with. Missed our flight even though we were there over 3 hours prior. Ruined the last day of vacation. Now we are waiting for the promised help in Amsterdam. No one is here. No one knows anything. Feel like crying"

Cons: "seats on Jet air flight are very uncomfortable"

Pros: "Captain was updating us with the delay status."

Pros: "The crew was astounding"

Cons: "I not get to go my flight, I couldn't get reimbursement"

Pros: "Na"
Cons: "They have a terrible communication problem, they never communicated why the flight was late, they never communicated what they were doing or what was happening. Bad customer service. Bad communication with the client. They told us when I asked several times that we would not lose our connection and that everything was fine and that was not the case. We lost the connection. No one told us anything. Another problem was that the girl in the boarding process removed the suitcases tickets from the boarding pass and did not want to return them, and held it without any cause. The flight staff went looking for us. Pretty sad and disappointed by their service. I understand that they were causes outside the airline but must communicate to the client. They cannot remain silent and say nothing."

Pros: "Seats are comfortable on Business Class. Service is good"
Cons: "Constant delays specially from CDG! Poor cabin service specially on this flight."

Pros: "NA"
Cons: "Both flights through Detroit were re-routed, our luggage was lost for 4 days."

Cons: "First class bathroom could have been cleaner and wider - very narrow, hard to maneuver"

Cons: "We didn’t travel to Detroit... we were re-routed 3 times and our luggage is lost, some really helpful ppl along the way (thankfully) and some really crummy ppl too... no in between... still not to our destination"

Pros: "Amazing crew and on time flight"
Cons: "None"

Cons: "Tell me i would misst the next flight and that my beg will not go to the final airport."

Cons: "CDG airport in Paris is a very inefficient and by far the slowest airport. I recommend other passengers to get to the airport at least 4 hours before their departure."

Cons: "See above."

Pros: "Food and wine. Entertainment."
Cons: "Sat closer to water closet. Maybe more air freshener in there."

Pros: "Food and drinks very good"
Cons: "In economy class the movies unable to listen to with ear buds. Bring my own next time."

Pros: "cbvghjkl;"
Cons: "mmmm"

Cons: "Lost my luggage."

Pros: "Crew was awesome!!"
Cons: "I paid extra for the seat, but there was a metal box under the seat in front of me that curtailed my ability to stow my carry bag, and my leg room. I am very diappointed that I paid above the normal seat charge as if there was a premium to this seat, but in reality it was a sb par seat."

Pros: "The crew was friendly!"
Cons: "Once again no vegetarian options."

Cons: "Better in flight entertainment"

Cons: "Air conditioning too cold. Wasn't offered an evening meal. My luggage went missing and I'm still waiting for it to be delivered."

Cons: "wine selection divider between seats"

Cons: "It was great trip thank you Air France"

Cons: "They lost my luggage :("

Pros: "The staff were very helpful and professional. The air hostesses regularly checked if I was ok and showed concern when I wasn’t. They made what seemed a bad situation seem bearable."
Cons: "The food was not very nice and the option I wanted had run out. The entertainment was faulty and had to be reset several times. The comfort was below standard and needs to be improved."

Pros: "Short flight so I can't really complain. It was no frills, standard small aircraft with no high tech entertainment system. Seats were fairly comfortable"

Pros: "Timely and smooth teansit."
Cons: "Food has a way to go to be appetising."

Cons: "My entire travel experience became extremely rushed and chaotic due to my flight being canceled and me being alerted -LESS THAN AN HOUR BEFORE IT TOOK OFF! This is unacceptable."

Pros: "Friendly crew, good meal and entertainment"
Cons: "Boarding agent forced me to check in my carry-on even though the carry-on fit in the cage and fullfilled all the requirements. I specifically called Air France prior to the flight to make sure I won’t have any issues as my 1st flight was operated by Delta and I wanted to confirm the luggage requirements were the same. My carry-on weighted only 5 kilos. I was extremely upset the way I was treated w/ the boarding agent behind the counter in Prague. On the top of that, her and the supervisor were very rude to my mom as they told her she had an extra carry-on which wasn’t the case. She traveled w/ a small briefcase where her mask for sleep apnea was. This is not considered an additional carry-on. The boarding agent (Czech lady and her supervisor) were not only rude but obviously lacked knowledge as well. My carry-on suitcase would easily fit in the overhead bin plus there was plenty of space inside the plane as it the flight wasn’t completely full."

Pros: "Fast and efficient boarding and friendly and efficient staff. Landed 15min ahead of schedule."

Cons: "Flight was delayed by 1h30min, so we arrived very late"

Pros: "Nothing"
Cons: "Airplane delay to take off 1 unknown reason After landing in Paris 50 min sitting inside airplane moving around Late for flight transfer. Sitting in Paris airport 5 hours. Customer service no working. Never fly Air France anymore !"

Pros: "Crew were pleasant most of the time"
Cons: "Boarding process is total chaos Took 40 mins to.check in at desk , pre ordered for wheelchair Never showed ...total zoo Beds advertised as lie flat bu they are NOT 180 degree flat , legs hang down - bad for circulation"

Pros: "The quality of service from the staff and their courtesy. A great asset of the airline."
Cons: "My luggage was left behind - this despite my being lifetme platinum."

Pros: "Flight attendant was very nice."
Cons: "We got socked with 40 Euro fees for our carry on plus personal item being 2 lbs over. The biggest problem is they were picking and choosing which bags they weighed. 10 people behind us and before us got in without incident. Plane wasn’t even half full so they were deliberately trying to make more $."

Pros: "Punctual, not crowded."
Cons: "Even though the plane was far from full, passengers were allowed only 1 carry-on item (no personal item), contrary to policy published online by Air France. This policy applied even to people with Economy Premium for the rest of the trip (which allows 2 carry-on suitcases, not a useful feature if one cannot begin with this number to reach the transoceanic flight)."

Pros: "Good cabin, but very conjugated :|"
Cons: "Too much of hassle checking in as the airlines partners with a couple of other airlines like Jet Airways, WestJet & Aircanada. The food was just okay and the cabin crew refused to serve extra butter. When you are serving extra bread, make sure you serve the butter as well. How could someone eat bread by itself?"

Pros: "Good service at gate and on board"

Pros: "The crew was good and very good pilot's"
Cons: "No leg room between seats"

Pros: "Very old plane with very poor screens where images was horrible"

Pros: "On time departure and arrival"

Pros: "Late, not enough legroom, smell from the toilet. Tiny TV screen, malfunctioning electronics, poorly maintained seats. Friendly crew! They looked tired, but they were still smiling while trying to keep passengers happy."

Cons: "The leg-space is very narrow The chair is very tiring No entertainment at all Food was tasteless But most surprising was that we were on stand by for our connecting flight. Though we bought the tickets months ago and we got our luggage checked in all the way to the final destination."

Pros: "Seats were comfortable with good recline. Food was good, but not excellent."
Cons: "They forgot the snack/breakfast service for the front right section of economy then had to rush it. Overall, the service was good, but some things just seemed off. An attendant call was never answered, etc."

Cons: "Our first leg from Paris was delayed and we missed our flight to Dubrovnik. We then had to hire a car and drive 6 hours to ensure we wouldn't lose a day more of our holiday."

Cons: "bad smell around my seat"

Pros: "movies were good, crew was great. Comfy seats. It was really as nice as an economy flight could be."
Cons: "delayed flight, hot overall plane, personal TV malfunctioned a lot"

Pros: "I like service of AF"

Pros: "Crew was very nice and helpful"
Cons: "Old airplane with very low amenities. Plane still had ashtrays"

Pros: "The airplane was new, good food and service."

Pros: "Pleasant staff."
Cons: "I sat next to an overweight lady and was incredibly uncomfortable my entire flight. There needs to be better regulation for overweight passengers to ensure that every passenger has enough room"

Pros: "Super comfortable even in coach (upstairs). I was impressed with service and quantity and quality of food. Would be pleased to fly them again."
Cons: "Seat did not recline as much as normal aircraft."
