Pros: "Hostes are great"

Pros: "The planets and stars we're aligned to provide an optimal trip. Price was a huge determinant for me...$800 RT Houston to Delhi just can't be beat. And, their arrival time into Delhi is so early (5: 20 am) that customs and immigration is a breeze."

Pros: "Decent food & entertainment but that doesn't change the fact that my flight didn't actually go to my destination, which is the purpose of booking a flight after all, no?"
Cons: "Rerouted us to Adana without warning. No help in rebooking flights. No instructions as to what we were supposed to do. Had to stand in several very long lines - incredibly disorganized. Lost an entire day of my trip."

Cons: "Flight was.cancelled.because.of snow in.Istanbul. Fine, that happens, but only solution was to park us in a hotel and tell us to wait. I did not see any serious attempt to reroute passengers and l had to buy another ticket in order to be back at work in time."

Cons: "Hot in the plane during and after boarding - no cool air. I have come to expect more from Turkish Airlines, and I hope they make sure they improve this aspect."

Pros: "Crew is very friendly. The plan is very clean and designed well and fashioned. The entertainer movie is good but the not all the shows."
Cons: "The air condition of the two planes I used was very bad. There is only one type of food for breakfast. There is no much more to watch besides movies; no sitcoms or decomntries found"

Pros: "There wasn't anything particularly special about this flight to make it stand out from other airlines. It was just a short 2 hour flight and had everything you needed."
Cons: "At check in, the agent said she had put me in the exit row, but I was actually just behind it."

Pros: "The service was great non stop and the goodies for the kids was amazing."
Cons: "All was good"

Pros: "basically the entertainment was the only positive part of the experience and the mac and cheese was ok"
Cons: "The airline apparently switched us to an earlier flight however we had received NOT A SINGLE email telling us that our flight had been moved. We had continued to receive emails for our original flight which still existed. Have no idea why they would move us in the first place and not tell us. We had to go through the hassle of getting switched back to our earlier flight which took an additional hour of dealing with people. This mimics our experience flying from Dalaman to Istanbul when our flight was canceled and we received no notification. They told us it was too early to receive a notification (we were there 12 hours in advance). However, had we arrived within the suggested window and found out it was canceled we never would have been able to reschedule to a connecting flight that still got us to Madrid in time.When checking our bags, the clerk tried to tell us that a backpack and small purse were too big to count as personal items even though they had been fine on ALL of our previous flights. I pointed out that individuals in other lines had larger backpacks that were being counted and he finally acquiesced but with a lot of attitude. The plane was then an hour late. The sign for boarding continued to tell us it was on time up until 45 minutes AFTER we were supposed to have boarded when it finally updated and said 'delayed'. The crew stood around laughing and providing zero updates as we all worried about whether or not we would make our connecting flights. TERRIBLE EXPERIENCE OVERALL"

Cons: "Aggressive staff, terrible food"

Pros: "Excellent food and services, both ground staff and cabin crew."
Cons: "Seat pitch is very short on the Airbus A330 for an average person’s height allowing for very limited body movability making it extremely uncomfortably especially on long flight durations."

Cons: "because of turbulence, they stopped serving food and beverages in the middle of their service but it wasn't that shaky. I've been in worse flights and they still served the food. they did not stop midway."

Pros: "Great airline but the food is restaurant worthy."

Pros: "The food is always good!"
Cons: "Thry promide Wifi but it didnt work Touch screens- the touch works really bad"

Cons: "My connecting flight was cancelled twice then delayed. I ended up missing my connection in Istanbul and having to overnight there. Turkish Airlines did provide hotel accommodation to passengers in similar situation, however only after wondering around the airport for over an hour to find the TK hotel desk and waiting for an additional hour to be assigned a hotel room and be transferred there, only to learn that I had to check out within two and a half hours after checking in to be at the airport 4 hours before the flight departs. When I finally arrived at the airport, I had to go through a security screening (because I was not suspicious for having entered the country and exiting only 5 hours later). When all of that was done, I approach the check in desk and asked if my seat can be changed, as I had spent the previous 2 days trying to get on my connecting flight, spending over 8 continuous hours at an airport and having had a nightmare night. I asked for an exit row seat or anything in the front of the plane. I was literal told that if I did not like the seat given I did not have to fly. I took the seat originally assigned and spent 11 and a half hours sitting next to a toilette on the airplane with a crying baby next to me and in front of me. To top it all, it took 2 hours to get my luggage once arrived at JFK. I usually love traveling on Turkish airlines and I understand not all of the above is directly depending on them, but considering how awful the entire experience was and how little I asked to be happy, I found them to be extremely unaccommodating on this occasion."

Pros: "The crew. Loved them !"

Pros: "I couldn't believe my seat in row 15 had so much room! It was incredible compared to usual economy. Don't know how this happened but it was a huge difference to the flight!"

Pros: "Expect this kind of quality and the level of service provided in economy class. Seats were comfortable, food was delicious, and the Stewart's were very accommodating. Made me wonder if I should of bought a business-class ticket"

Pros: "As usual, crew and food were superb!"
Cons: "Very long waiting before boarding. The flight was late, and the boarding was exhausting."

Cons: "Due to weather, flight was delayed which is understandable. What is NOT were the multiple gate changes on opposite sides of the terminal with NO notice or announcements. This seems to be routine practice with this airline in Istanbul. It is UNACCEPTABLE especially for people who are traveling with young children."

Pros: "Plane wasn’t full and left and arrived early!"
Cons: "Offering some kind of beverage"

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "A bigger plane."

Cons: "Baggage handler lost my bag, grabbed it off plane cabin, never found"

Cons: "Bumpy ride in CLT but uncontrollable"

Pros: "Great wifi. Nice comfortable seating. Great entertainment selection"

Pros: "We arrived safely and so did our luggage."

Cons: "Easy and fast flight"

Pros: "Very courteous crew.pilot was amazing!! Landed in tough wind"
Cons: "Turbulence"

Cons: "Rude gate agents who did not inform passengers timely about the 2.5 hours delay. Post the delay after the expected departure time, etc. Terrible experience."

Pros: "Flight crew very friendly."
Cons: "No entertainment so 1 star rating. Kind passenger switched seats so I could sit with my husband and son. Would have had to sit behind them if not for her. Paying extra for isle seats was a surprise."

Cons: "Wish they had told me there was a shuttle to other side of airport. Had not been to this airport in many years."

Pros: "We arrived on time."
Cons: "These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away."

Pros: "Crew did their best!"
Cons: "Our flight was delayed over 3 hours. Other Advantage members have already received bonus miles for their inconvenience. I am also an Advantage member and have not received bonus points and am unable to get ahold of anyone."

Cons: "The flight leg PHL-LIS was the most unconfortable transatlantic trip I ever experienced. The plane was small, tight and no head support made this the worst transatlantic flight of my life, easily comparable to any low cost airline."

Pros: "Getting out of the plane! and the landing was very good."
Cons: "Bad service no entertainment besides a one very childish movie. My tray stayed with me the whole flight, I had almost to beg to take it and never s flight attendant seem happy, pleasant or even profissional. The landing by the pilots was amazing."

Pros: "Other passengers were friendly?"
Cons: "I was traveling alone with my tired, cranky 13 month old. I get that it's no fun for anyone, including me, to have a tired toddler on the flight! But from the moment we boarded the flight attendant was unfriendly and unhelpful. I asked for help putting a heavy bag in the overhead compartment. She half-heartedly tried and then told me it "didn't fit". By simply turning it on its side, I was able to easily make it fit, but it was uncomfortable for me to have to do so while also holding my baby! The flight attendant then commented that I couldn't have the child in a carrier during the flight (something I am well aware of!). She also neglected to offer us a snack later on. Overall, she was rude and inconsiderate and made a difficult trip more unpleasant."

Pros: "Not much."
Cons: "There are NO ENTERTAINMENT, and I had two flights that were more than 5 hours each. It was not operated by British, it was actually American Airlines."

Pros: "Crew and promptness"
Cons: "No entertainment for each seat. No cellphone charger."

Pros: "The flight had a delay of 4 hours in Philadelphia. I missed the appointment in Lisbon for which I was flying in the first place. Furthermore, I had purchased the ticket with the intent of flying with British Airways and found myself in a charter from American Airlines. I wish to be compensated for this mistake. Thank you"

Pros: "Boarding was fast and easy gate agents were awesome."
Cons: "Older plane. Very uncomfortable"

Pros: "The PWM airport, ALMOST makes air travel tolerable. Great little airport. Crew was pleasant, Seemed to enjoy their work. That, alone makes a huge difference in an industry that truly doesn't put customer service anywhere NEAR the top of the priority list."

Pros: "Very comfortable and enough drink service."

Pros: "Flights were on-time, planes were clean/newer, snacks were good."
Cons: "Their boarding/de-boarding process was quite inefficient - they have boarding zones, but then you just go to a shuttle and it's a free for all at the plane."

Pros: "Punctuality"
Cons: "Small plane with no leg room"

Pros: "Everything"
Cons: "Nothing"

Cons: "Flight was good until, after arriving 30 minutes early to PWM, our plane had to wait about that much time for our gate to open. Once pulling to the gate we waited another 15 minutes for someone to figure out the walkway and open the door tom the plane-- all with no communication from the crew."

Cons: "i decided to purchase a separate direct flight at a different time instead of changing my flight, only to be informed later when i tried to hop on the back end of my original flight, that they had canceled my ticket since i hadnt boarded on the front end of that flight. i had spoken to a customer service rep about my option before purchasing the extra ticket, and she did not mention that this would be an issue. then i had to pay extra to get back on my original flight."

Pros: "I booked the flight specifically because it was advertised and booked on British Airways, which is considered a nice international airline to fly. The flight was swaped to American Airlines, and I was put on an international flight that was archaic, I would have been better off flying a prop plane from the 1970's."

The flight was swaped to American Airlines, and I was put on an international flight that was archaic, I would have been better off flying a prop plane from the 1970's."

Pros: "Quick and easy"

Pros: "Nothing"
Cons: "I never even made the flight because they kept jerking us around"

Pros: "The flight was smooth and the coastline views were amazing."
Cons: "No in-flight entertainment. Poor quality sandwiches."

Cons: "flghit Porto/Lisbon 1 hour delay"

Pros: "the crew was nice"
Cons: "We had to sit on the tarmac and deplane just to get onto another flight where I no longer had any power to charge my devices"

Cons: "Very crowded plane."

Pros: "Crew was efficient and helpful. Captain kept us posted along the way. They also keep air flowing when we were delayed to take off so everyone is comfortable inside the crowded cabin."
Cons: "Crew should try to wake me up for meals. Luckily my fellow passengers did. Otherwise I would have missed all my meals."

Pros: "Crew was very accommodating in light of the maintenance delay. Especially for those of us with small children."
Cons: "Look, delays suck. We fly about only once a year, and we ALWAYS have a delay. ALWAYS. Air traffic control at Newark will delay a flight for a hangnail."

Pros: "Emergency exit"

Cons: "arrived 24 hours late. had to stay overnight in Newark. And United lost our luggage. The worst trip I have ever had."

Cons: "the stewardess and steward bumped seated me continually when I complained she told me it was tight inexcusable"

Pros: "On time departure and arrival and a friendly crew helped keep this flight smooth despite some turbulence. The fact that there have been electrical outlets on this route for so long is a testimony to the Continental heritage."
Cons: "The seats in economy are just so tight that sleep on this short overnight flight was almost impossible. The lack of more recline (as in the recarro sears used on the LH/LX products) and short pitch make it hard to either work or sleep. The small plane size makes this sardine feeling worse and slows service to the rear of be craft."

Pros: "It’s existance. Informative capt."
Cons: "Late almost 3 hours. Sketchy bev service. 50 seat RJ."

Pros: "Nothing"

Cons: "JUST BEFORE BOARDING THOSE OF US PASSENGERS NOT ALREADY BOARDED WERE TOLD WE COULD NOT BRING OUR CARRY ONS WITH US AS THERE WAS NOT ENOUGH SPACE TO STOW THEM OVERHEAD. SO WE WERE TOLD TO SEND THEM DIRECTLY TO OUR FINAL DESTINATION. WHEN I BOARDED THE PLANE I COUNTED 7 OVERHEAD STORAGE BINS ON THE OPPOSITE SIDE TO MY AISLE WHERE I WAS SEATED WERE NOT FILLED AND THERE WERE SEVERAL SUCH BINS ON MY SIDE OF THE AISLE (I DID NOT HAVE TIME TO COUNT THEM BEFORE I SAT DOWN). I ASKED AN ATTENDANT WHY THIS WAS SO GIVEN WE WERE TOLD THE BINS WERE FILLED JUST AS WE BOARDING FROM THE DEPARTURE AREA. SHE WAS POLITE AND SAID SHE WASN'T SURE ABOUT WHO MADE THE ANNOUNCEMENT IN THE TERMINAL BUT THAT IN ANY EVENT MY CARRY ON WOULD ARRIVE SAFE AND SOUND IN VANCOUVER - IT DID BUT WITH MY BOOK FOOD SNACK WHICH i HAD INTENDED TO USE WHILE ON MY WAY TO CHI. AND VAN."

Pros: "First time first class flyer. It was great!"
Cons: "Being separated from my wife in seating when we booked before others that we talked to!"

Cons: "Even though I am a frequent flyer with a Global Access card, I was select for enhanced security check. I paid for the Global Accessmcard especially sofas to avoid this. United said it was a TSA thing while TSA said it was at the prerogative of the airline. Why did this happen? So much for TSA Pre or Global Access."

Cons: "See above"

Pros: "Arrived early"
Cons: "The plane dropped during decent."

Pros: "4"
Cons: "4 hours late, bad food, stressed staff."

Pros: "The flight was ok."

Pros: "The crew was nice and the area was clean."

Pros: "nothing"
Cons: "it took me three days to get home. the first plane had a mechanical error. the second flight united booked me on was over booked so i didnt get a seat. the third flight they tried to send me on was also over booked. luckily someone volunteered to give up their seat."

Cons: "Seating next to the bathroom is gross"

Pros: "Friendly and polite! Crew."
Cons: "Middle seat. Space too small."

Pros: "It use to be, I could put up with the lack of comfort and services because the cost savings made it bearable. But thes days, the basic ticket costs are high and increasing despite ala Carter pricing. The flights are always full and the number of flights are down. Airline profits are at a peak yet very little is flowing back to improve the flying experience."

Cons: "No agent to check in when I arrived at airport. Only at gate. No advance check in or advance seating. Allowed passengers to have more than 2 bags. Flight was late. No help getting to next gate or holding aircraft. Absolutely uncomfortable sitting."

Pros: "That I got a refund, although that should be a given"

Cons: "Canceled flight, booked me an impossible connection, put on stayby when I get the tickets months in advance. Offered no vouchers and made me fly out on a diffrent day. Hs aircraft delays on all flights"

Pros: "Nothing."
Cons: "Never flying United again. On my way to the airport in Portland I got a text from United that my flight to Newark had been cancelled and there was no way to fly me out of Portland to San Diego that day. My sister had to drive me to Boston so I could catch a flight to San Francisco, which took 6.5 hours because it flew over most of Canada for some reason AND had three babies that cried from start to finish. Oh and because I was a late addition, I had a middle seat. The second I turned my phone on after we landed I had another yet another text from United saying that my connection to San Diego had been delayed three hours and wouldn't take off until 11:15 pm."

Cons: "Cancelled and rebooked on a different airline with a long layover."

Cons: "Tried to get assistance at the United desk where my gate was located at and they could not answer any of my questions and would not assist me or many others who had the same issues."

Pros: "Nothing"
Cons: "Payed to upgrade seat was not comfortable and person next to me kept moving onto my side. Flight was 2 hours late so I missed my connection and had a terrible time to find a flight home. United staff was not helpful and kept telling me to go somewhere else for help. No food was served only tiny packet of way too spicy pretzels. Sat on the runway for an hour. Flight crew said 15 min and it was much longer. Crew seemed to be really confused."
