The price was great but did not realize I needed to pay extra for luggage (a small suitcase) and there was no service for drink or food unless you pre ordered a meal. So good to know! Check in leaving JFK was pretty long and not so smooth but all went well! Intertainment was fine and seats comfortable!

The flight going to Paris was fine, but the return flight from London was the issue. In over 40+ years of flying back and forth to Europe I have never had an airline weigh my pocketbook to be added to the weight my carry-on baggage for a total weight. I feel this is extreme and cheap and just an excuse to get more money from the passengers. The weight of my pocketbook is not going to cost the airline more fuel to fly the plane.

I believe the only thing I did like about the trip was the easement of getting checked to board the plane. Other than that, maybe just the price of my flight.

Where to begin, first of all the flight was delayed. And not just one or two hours, but almost 5 hours! The communication from the boarding crew was atrocious, as they did not keep us informed until maybe an hour after the fact that it was already delayed. After finally being cleared to board we were all cramped and rushed on a shuttle from the waiting area to the plane. I've been on cramped planes before, but maybe not this badly. I received a middle seat, which was alright, but the amount of space to move around in was unacceptable. I attempted to load my carry on in the storage compartment overhead but it was all taken up. That made matters worse in terms of having space to stretch my feet out, as the person's next to me were not the kindest and kept cramping me even more. The delaying of my flight made me miss my check in to my hotel two hours later. I lost most of my day I'm being able to have free time before the check in due to it. Overall, I was not satisfied one bit with the airline service. I just hope that my return flight is a more pleasant one.

I've been traveling to Europe and back for 40 years+. This is the first time I have ever had to weigh in my pocketbook along with my carry-on bag - that's outrageous!!! I realize that you are a discount carrier, and one has to pay for luggage, but this is ridiculous!!! You go to the extreme, and a women's pocketbook should not have to be added to the scale along with any other carry-on bags for a total weight of 10 Kil. That's extreme and very miserly in my opinion and not a positive refection on your airline!

There was water to drink

Plane felt like a 1990 air France flight. Cabin dated. The least amount of room I can remember on a plane. When sitting upright and the person in front reclined, i looked at their head and if I crossed my arms, it would touch the seat in front. Could not pick up pillow that dropped on the floor, could not bend around the seat in front. Very hard to get out to use the toilet. Felt very claustrophobic.

The price was good for a round trip flight. The movie options are good as well. The crew was okay. This was a full flight and no one went above and beyond for guest service but no one was rude.

The boarding process was extremely disorganized. The original time to take off was 3:30 (15:30) we didn’t take off until 4:45. It took 45 minuets to board the plane. Everything on this flight you have to pay individually. This is an 11h 30 m flight and bags are not included and a meal is not included. Even a small bottle of water, or coffe or juice will cost you $3.00

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.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

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.
