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

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!

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Flight was late over a hour just like the first one. WiFi was down.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

Lost luggage, 2 bags were badly damaged and one of the bags came open.

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

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.

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

The United flight was excellent! The flight attendants were attentive and nice, and the food was very good! And the glasses are larger than on Lufthansa flights! I don’t want to have to ask for 15 glasses of water because their glasses are ridiculously small!

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

The plane was 3 hours late. What more can I say?!.. This, plus my horrendous experience of the second leg of my trip in where the plane had to be boarded (off and on) without escalators.. but not-covered outside regular steps…!! No… this is my last flight with Lufthansa!! Never again!

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

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.

Missed this flight. $5000 to rebook next day. Horribly rude staff in Frankfurt. Everyone we encountered was either not helpful or outright mean.

Condor's computers do not work. They do not leave enough time to catch a connecting flight. Condor had to book passengers on a different airline to make their destination. They lost my niece and nephew's luggage. The bathroom had pee all over it before the flight took off.

Awful!! We got stuck in the passport line for two hours. Condor acknowledges that the lines are really long but says it is not their problem and would only rebook us in two days. We are stuck in Frankfurt for two days and it cost us $500. Condor stated that they gave us a 1.5 hour layover which was more than enough time and in the next sentence said, yes we know the lines are a problem.

It was freezing cold, the flight delayed and then I got rebooked to a different connecting flight with a four hour waiting time even though I would have easily made my initial connection

Absolutely the worst food I ever had on any flight. Half of passengers simply didn't eat their meals, as I noticed.

The crew was friendly, but the comfort of the plane and the food definitely had room for improvement.

The seats are too close to the ones in front.

Seat was the worst I ever had in an airplane

I will definitely recommend your service. This is my first experience with Condor and so far it was great!

A flight attendant placed a meal on my tray. I was in 44E. The passenger who was in 44G had gone to the bathroom. I ate the meal. When the passenger in 44G asked where his meal was the flight attendant put the blame on me. She claimed another attendant put the meal on my tray. She then claimed when she gave me the meal she asked me if I had ordered a special meal. She did not Worst experience I have ever had with a crew member.
