The service was poor and not friendly. They over sold the flight and put the stress into customers. They kept the flight so cold that I had 2 blankets and still shivering. The seats are so darn tight that the people next to me didn’t fit and I had to sit at a angle for 5 hours. What is dissatisfying is that airlines will continue to treat customers without compassion. We pay for a service and should not be yelled at when you over sell a flight and demand people to check in carry on bags.

On time in spite of a late start Gate attendants were nice and helpful Comfortable as is possible in economy without spending a lot more money. Food (pretzels and drinks) as good as possible without spending more money. (I remember the good old days when you got much more in seating and food for your money)

This flight I had a window seat and I felt like I couldn't get up to stretch my legs or use the bathroom. (I am 70 and 4 hours is too long to sit) I usually get an isle seat but ALWAYS have to give up my bag at the gate - my bag which you tell me I can bring ON the plane with me. I do not like having to waste time claiming my bag that you told me I could have with me on the plane. I can pay $25 for that privilege!! The flight attendants always seem like they have their defenses up. One even held up the people trying to board so she could serve a drink to someone in first class. REALLY?? They couldn't wait till the plane was loaded?? I gave this flight a 'good' rating because it was mostly as good as it is going to get with economy passengers needs stripped to the bare minimum.

Added $40 bucks here, $12 there, $5 here adds up since that's per person each way. If you don't have bags to check or you pay to join their frequent flyer program, it's reasonably priced. Otherwise, Cha ching!

Getting home

Being nickled and dimed for everything, rude service and completly uncomfortable accommodations. I was coughing bc we had to run to the gate. I asked the flight attendant for down water and he have me a tiny cup with 1/4 of the cup of water. Water would have solved it but due to their careless mess I couldn't rest or stop coughing. Then a bottle of water is $4. Awful turbulence, though not their fault, would it provide water till it stopped. Forced me to stuff my purse into my bag which caused extra creases, I did not have to do this on the flight there, when I explained that they said too bad or pay $50 more. Every step of the way was rude, careless and inconsiderate

I have never seen a gate attendant call each person by name as she scanned their boarding passes! At Delta I felt welcomed by every employee. Even the pilots greeted the passengers as they exited. All the other airlines just want my money, they want to cram me into smaller and smaller spaces and want me to sit there and shut up so they don't have to interact with me. I will fly Delta every chance I get, even if I have to pay more money.

I booked with KLM (sky team) two separate return bookings on via SKY TEAM JFK > heathrow (delta) Heathrow > Amsterdam (klm) On the return leg, I couldn’t check my bag all the way through to JFK even though I stayed on SKY TEAM carriers. That should be possible, otherwise the value of staying in SKY TEAM isn’t as valuable to me.

Delta Flights are always enjoyable and the staff is always treats you with courtesy

The only thing I don't understand is how the planes are loaded. and this is only a comment and I know you and others carriers have there way of doing things. I just don't understand why you load the first section of the plane first and the back of the plane last, It looks like you would want to load the back and come forward so everyone is not getting hit and stood over while everyone is loading.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
