Everything went very smoothly. Airplane food simply is never great but they were quite generous and very attentive. I was impressed.

Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!

Food TERRIBLE! In First Class- so bad - why was it so much better 20-30 years ago? Comfort-awful-would rather have the old, plush First Class seats than the new hard - too short seats in the new pods -would advise avoiding Delta for any International Flights.

The airport process and boarding were fast. The airplane crew were nice but the food was bland and the seats extremely uncomfortable- my seat had an issue and couldn’t move back and made noise .

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Horrible. Flight ORD to CGH was okay, but Paris was a nightmare. Old planes, delays, involuntary downgrades, broken planes, terrible communication. CGH to CPT was my worst flight ever.

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

Lost luggage! No representative of the airline present at the airport. Air France contracted the service out to a 3rd party service. The service has no ability to track the missing bag or provide a time frame on its arrival.

Very disappointed in the food selection. It was not good compared to other airlines.

It was delayed and I missed my connection to BHX

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Good flight. Mass boarding. Seats fairly comfortable. Food okay although may have upset my stomach a bit.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

Everything was perfect. I would’ve liked better selections for entertainment, but I slept most of the time, so it wasn’t really an issue.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

It was a fairly old plane in which you couldn't buy an internet connection.

It didn't happen. SAS csncrlled and it was very difficult to convince the 3rd party they did. Not good on the 3rd party program. I don't think they trust their customers, much less being able to help them. I have had several nitemaes using 3rd party this trip and WILL NEVER use 3rd party again.
