I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

Brand new plane lots of room the snack was very flavourful and enjoyable

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

Seats were very tight with poor legroom - and I am average height. During the 12 hour flight, tiny paper cups of drinks we're only offered during the super and breakfast services, with the crew nowhere to be seen in between. One of the bathrooms was out of order, leading to long lines waiting to use the remaining two available to the economy class passengers.

short flight but we still got a very nice lunch and the crew did an excellent job in taking care of us

For that price on Business class, I expected to have the pod seats. These were configured as 2/3/2 and my seat mate talked half the flight with a friend across the isle, loudly. Very uncouth.

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

Very comfortable in business class. Excellent service. Good food. Smooth trip.

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

This flight is a quick way to get to Chicago, but a bit expensive.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

Requested early boarding to disinfect seat, tray table, etc. before general boarding. Instructed to board after wheelchair passengers. Waited on jet bridge behind 12 wheelchair passengers. Stopped immediately after entering plane to wait for gate agent in rear of plane cleaning a seat that was wet, got to my row and found both seats adjacent to mine already occupied, with the lack of room making it impossible for me to clean my own space and defeating the purpose of my boarding early. Cleaned the armrests and tray table as best I could.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

I was downgraded from first class to coach due to an airplane change. They pulled me out of line and I was the very last person to board the plane stuck in the middle seat with no overhead place to put my carry-.on. Very poor customer service.

Seat comfort was poor (no lumbar or lower back support).

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

STOP MAKING THE SEATING SO CRAMPED. WE NEED A PASSENGER BILL OF RIGHTS!

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

We had several flights and they were all on-time and flawless
