Flight was 2 hours late, causing a missed flight. Baggage took 90 minutes to arrive. The airline provided no info on connections as hundreds of passengers stood around for an hour and then chaos reigned as all rushed to get rebooked in only two lines. Nobody got rebooked until the next day and had to stay overnight in hotels with a voucher that provided only minimal food after a 15 minute walk to a fast food restaurant. the following day we were rebooked to Copenhagen rather than Berlin, with no guarantee of a connecting flight. I was forced to buy another ticket on another carrier in order to make my own wedding.

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

Ground staff at Manchester very helpful

Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros.

We arrived minutes earlier.

The cabin lights after dinner were supposed to go off so people could sleep. The lights were going on and off uncontrollably the last few hours of the flight. Flight attendant said the plane had issues with the "control panel because it was an old plane". The worst part was when a female flight attendant wouldn't move her feet over a few inches while sitting in her chair, so that I (a pregnant woman) could use the closest bathroom to my seat in the back cabin. I had to ask her twice and both times she confirmed "She was on her break and would not move her feet" so that I could use the bathroom. Also note, the seatbelt sign was off but that wasn't even her excuse. The bathrooms were dirty and the toilet seats need to be replaced to be asked to sit on those is degrading!

I loved the timeliness of the food service, and the options available for beverage service. The selection of movies and music available on the TV screen in the seat back was great, and allowed the time on the long plane ride to pass a little faster. The captain was extremely informative, about our flight path, the wind conditions, weather at our destination, etc. I particularly enjoyed the information he provided, because on some flights, you rarely hear from the person flying the plane.

The boarding process was interesting: those that needed assistance and business class 1st (understood), but then front of the plane, back of the plane, and finally the middle. I don't feel this made things go any faster - we still waited in line for quite some time in the jetway. I don't understand having front, back, and middle. Just let all economy get in line, or do something efficient like load the window seats first, the aisle, and for the seats in the middle of the plane, have the middle seats load 1st, and then the aisle seats. Seats got uncomfortable during the flight. Also, the person in front of me reclined ALL the way, so the top of her seat was only a few inches in my face. Most flights I have been on don't allow the seats to recline that far. I could barely get out of my seat to get up and go to the bathroom.
