It was great, I’m very grateful for the pilots and crew flight attendants for everything.
It was great, I’m very grateful for the pilots and crew flight attendants for everything.
Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick
The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.
Delay and keep changing gates. I have to run around from B to C then to E.
I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.
The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!
Flight was great. Efficient boarding. Short flight. Early arrival. Friendly flight crew. The entertainment system did not work well. Could not access it until the aircraft reached 10K feet or more. Lots of glitches.
A bit rush for transit. Food and entertainment are not available
Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.
Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.
The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.
Everything was very good, except that the plane was an hour and a half late
flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work
Light and recline did not work on my seat. Very uncomfortable and could not read in the dark
Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.
I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant
It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat
Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks
Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.
Very nice and friendly crew. Boarding system can be improved.
Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan
I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.
I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude
Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!
Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.
This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable
Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.
You were more on time than United. I'm so over united delays.
The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.
I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.
I liked the comfort of the plane. It was unexpected from past experiences.
BEWARE!!! Iberia changes your seats at random. I paid for a window seat and they changed it to one in the middle aisle resting against the bathroom- can’t lean back + hear every flush. This on a 11 hour flight.. There were families that were broken up with separate seats all over the plane. Lots of upset passengers showing their seat confirmation to the besieged and helpless airline steward. Also, the gluten free meal was tasteless.
Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.
ground crew and check-in was pathetic - insisted on charging me for luggage even though the ticket said it was already included. They also accidentally sent my luggage through without a luggage tag and had to retrieve it. Generally, it was like a bad movie.
Moved the flight an hour later, were not reliable about confirmation, website didn't work, no gate information, boarding was a mad house. Flight itself was fine and short. Organization needs work.
The app on phone and the online check in is not good, it would not give me the option of Spain or Madrid City in the drop down menu and I couldn't move forward with online check in.
Flight was delayed 3 hours and 15 minutes. The delay caused me to miss my tour group due to arriving late.
As always a terrible experience. AA stole a day from my vacation days planned to be spent with my Family. Response: delays related to weather issues.
It was a wonderful experience with great food, great staff, and no difficulties boarding!
Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.
Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons
The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!
Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.
I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.
The entertainment selection was ok, but overall not bad! The crew was great.
Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.
bad, made it to connecting flight and they didnt let me board
We were never able to take this flight because our first flight from Austin to Dallas was cancelled.
Our flight was cancelled on Sunday morning. We were supposed to take a short flight to Dallas from Austin, then a nonstop to Barcelona. We were rerouted from Austin to Miami on American Airlines due to storms we sat at the gate for 2 1/2 hours, pilot announced we needed fuel. In air pilot said we were rerouted to Fort Myers 30 minutes from Zmiami. Sat on tarmac waiting for a gate. Deplaned at 10:09. Pilot gave conflicting info about what to do. Missed Miami flight to Barcelona. Pilot announced crew was timed out and we would have to wait for a new crew. Waited a couple of hours. Got to Miami at 2:30 am. Gate agents at Fort Myers told us to go to D30 for hotel vouchers. No one was there. So we slept a little on the floor. Husband is 80 and I am 74. Rerouted to JFK at 9:54 am on Monday, then flight to Barcelona at 5 pm. We arrived in Barcelona a day late and missed the first night of our Oceania Marina cruise. We feel that we are due a lot of compensation for this trip from hell.
The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?
