It was clean, and the crew did great!

Way off schedule, way to tight of space, no way to sleep being such a late flight! As far as a beverage, they were out of everything!! Nice air line for quick trips,but to fly for 4 hrs at night from leaving at 12;00am, just impossible to sleep or really relax.

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!

With lack of reclining seats and no complimentary snacks or drinks at all, the comfort scale is lacking. Even the tray tables were replaced by miniature, undersized, pieces. Even with the discounted prices, it’s hard to want to fly with them again.

Our flight got canceled due to airport issues at our destination. United canceled the flight but had no alternative flights to get us home. Flights the next day were full. Took over an hour with the service desk to reroute tickets to cancel them and to get bags back then took two hours at baggage claim to get the bags back. Customer service was basically useless. After all that, we didn't get any of our money back! I will be avoiding United airlines. Flight cancelation was not their fault but the way they handled the rest of it was embarrassing.

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.

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,
