The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

If I had a chance to rate Turkish airline in negative I will definitely give -100. Worst non professional attitude of ground staff at Istanbul. If I was a owner of Turkish airline I would definitely fire all check-in staff who was on duty for this flight. Rude attitude to all customers. Non availability of food options. Chicken and fish option was finished within 8 rows and only pasta was available (seat rows 25- last row). Seat Front glove boxes were ripped and all stuff was dropping on floor. Flight crew was trying to pacify the customers but this is sole responsibility of the manager who arranged / booked the food for this flight. He must be removed from this position as he has no idea about his job. It was worst flight during my whole life. Never booking again on Turkish airline.

Our flight attendant was stellar with great anticipation and attention to details. Food was very good, and overall flight, though very long, was really good.

Turkish Business Class is a wonderful experience, and the best inflight dining experience I’ve had to date.

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

Delicious food, comfortable and clean plane. It's a little cramped in the hall in front of the gate.

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Turkish Airlines is amazing. I have a problem with the ticket I purchased through the kayak website. I have filed a complaint related to the fact that I was contacted by phone on the day I purchased the ticket and told that the amount that the ticket had been advertised for was not accurate and that I had to pay more. This is totally fraudulent. I will look into addressing this further tomorrow and will never ever use kayak again.

Definitely not a fan of Turkish Airlines, their seats are very uncomfortable. Felt very cramped up. Food was very poor in quality too, very little to drink during service.

The seat in the 787 was broken and did not keep us in the upright position. Also the entertainment system was broken for some channels and only had audio and no visual display.

Long haul flight need to have better snack/food options. Toilets were not refreshed regularly. No toilet paper or hand wipe tissues.

roomiest flight in economy I've taken in years. Excellent experience!

The entertainment system was not working, they tried restarting it couple of times but it did not fix it. We were told to contact Lufthansa costumer service after the flight for some kind of reimbursement. When costumer service was contacted I was told no reimbursement for entertainment system malfunction per policy.

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

Food was much better than my outbound flight. On-time. Good service. I had a problem with my entertainment screen, but the attendant fixed it promptly.

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.

The only thing that the airport can improve which will help Lufthansa from delay flights is to warn the passengers that are flying to the USA to be earlier to the gate due to the documents check that in our case delayed the flight

SEA to Munich flight was turbulent and you could hear rattling in the plane. The food was TERRIBLE, return flight was better. We will not fly Lufthansa in the future.

Flight was good, staff members were helpful and energetic, food can be more tasty.

Fast boarding, great entertainment on board, lots of updates from the capitan during the trip, no lost luggage issues
