I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

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

Klm start boarding while somw air issue in the plan

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

Again poor use of old aircraft and old business class seats that show there age.

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.

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.

Food is delicious I’ve tried Thai green chicken curry and it was perfect!

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 very late, meaning a missed connection in Frankfurt, and staff completely unhelpful or just absent. Handicap accommodations, reserved in advance, somehow never made it through the system for the second trip in a row!

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

During the boarding process women with small children were not invited to board first and were clumped into general crowd boarding, also during the 3 hr flight there was no food or water offered and I was traveling with a small child who needed water. I would appreciated that next time Luftansa informs that on 3 hr flight there would be no food or water offered so that I can prepare for the flight. In addition, traveling to the plane with the bus and then climbing up the stairs into the aircraft with small child and overhead luggage was probably the worst experience that I had in years traveling. Overall, will try to avoid traveling with Luftansa by all means. Thank you

Someones phone kept ringing and the flight assistant did nothing about it. Not even an announcement.

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

ok. It's a short flight and it was delayed, hence the ok rating.

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

Adequate to good experience. Comfort was mediocre but everything else was good..

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

Had a very bad experience flying out of London. Our initial flight was cancelled without notice and the next flight had a layover of 8 extra hours. Me, my husband and my 8-year-old were already sick, and this further added to our problems. We paid extra for the seats: I was not even given our chosen seats which we paid for months before the trip. We were shoved into the available seats which were middle ones in the back (we had paid for front window, aisle, aisle). The seats were so uncomfortable and getting out of middle seats every so often (with a sick child) was a task. We had initially chosen British Airways because of the short layover, however, that went out of the window. Although unexpected things happen all the time and I understand customers have to adjust for the unplanned, however, how the airlines react and make the passengers comfortable during that time is the real test. We were not given any compensation for food or any arrangement to stay comfortable during that time. In fact, our paid seats were taken away as well.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.
