Delta flight was on time, seats were comfortable, and crew was nice.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Better seating for sure. The seats were so close together for such long flights.

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Food is terrible. Flight is outdated and seats are not comfy.

Check-in at 4:30 am in the morning was very quick and efficient.

Every single flight with them either cancel or delay for stupid shift. They are full of excuses.

After checking in online i called United to make sure I have special food ordered ( kosher option). Representative I spoke with on the phone with assured me that special meal was ordered. On the plane, during meal service I was informed that there is no note about it and no kosher meal was ordered for me. Flight attendant said she will check if maybe was a mix up and meal is somewhere. But never came back with any update. So entire flight with no food...

Ground staff were excellent They helped to re book when our flight was canceled

First flight was delayed taking off and delayed getting to gate when we landed. Therefore made the connection time very stressful. barely made it to the connecting flight. We were forced to check our carry on luggage. Then you lost one of pieces of luggage when we got to Detroit.

Some of the issues with my UA flight to a connecting flight: United said the SF to Frankfurt flight was getting late making us miss 10:50 flight and could only put us on a flight that left at 4:15 PM from biz to coach. then they canceled the ticket on the connecting flight. I didn’t have a seat, etc., etc., and over an hour dealing with UNITED blaming Lufthansa and Lufthansa pointing to UNITED. The flight itself was fine (food sucked) and we landed in time that I could’ve made the 1050 flight. but the LH gate agent said I couldn’t get on because United issued the ticket and only they could change tix back. Gave up and wasted the next five hours plus of our vacation and ended up being totally wiped out by the time we reached the hotel.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

British Airways staff are very polite and willing to help.

Any sort of gluten free snack option would be nice

They lost my luggage and it didn’t get delivered until the next day.

Would have thought that they would gas up plane before everyone got on board

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Crew was not happy. Very uncomfortable seats. When person leans back in front of you the screen is too close to me. Food was awful.

Lufthansa charged me $280 to take skiiis when in the US the boot bag and skiis are one check-in bag. This was not advertised and a real shock at the airport. They only took the boot bag as a check-in item. The seats have been squeezed together like any economy airline and legroom is not as good as it used to be. Otherwise, the flight was fine and staff was helpful for making my connection.

On board Entertainment and crew services were absolutely trash! Neither me, nor any of my 40 family/friends members are flying Lufthansa again!

This is my second time to fly this year with Lufthansa and both times they dropped the ball. My ticket was very cheap and l would not be honest if l said that l had some high expectations for that price. Fly delay 6 hours. Screen in fey seats around me didn’t work. Food for dinner was ok but breakfast was so poor. We had connection in Frankfurt for Vienna. Because of delay they gave us fly with 30 min layover time. We got to Vienna but our baggage was late of course. Long story short it took us almost 24 hours to get to the final destination. Very bad experience
