Arrived safely, only a little late.

Duty free? Marks and Spencer? The cart and crew kept going by but never offered drinks. So thirsty!

Safe landing

Was charged 65 pounds for checking one bag. This was a big news to me. BA claims it was because I booked through Kayak. Would not have booked the flight. Luggage cost is almost superior to flight cost. Forced me to check my overhead luggage. Flight was delayed one hour because we had to go back to gate to rebLANCE WEIGHT

Had to sit in the middle row and I wasn’t given the option to get an aisle sit during check in.

No flexibility for seats

Entertainment system great. Individual choices include recent movies. On board staff very nice

We had issues with baggage. Delta was supposed to transfer 4 bags to Disney for Magic Express transportation. Only 3 went. Disney tried hard to fix problem, and even gave us something to ameliorate the situation. Delta took hard line, wasn't helpful and gave nothing. It took 2 days to find bag.

I am used to flying Frontier because of cost but recently traveled Delta and boy did I feel completely spoiled! Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

nice employees

for the second time on this flight, the onboard devise for credit cards would not accept mine. this is the same card i used to book the flight. i complained to british air last time but they obviously haven't fixed the problem. there seems to be a problem using american credit cards these flights. is is a problem because nothing is free. luck;y a flight attendant did feel bad about it and gave me a glass of water

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
