Departure was right on time and we actually arrived 15 minutes early.

The inflight monitor worked but none of the data (GPS altitude or speed) was working.

I have always known of airlines to offer preboarding to those military members in uniform or on official orders. Delta took it one step further and allows prior service members to board also.

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!

Not much to like on this leg of my flight

Was over an hour late to board and depart. Missed connection in Seattle, was then given printed paperwork for new flight which would not get us through security and then had to go back to main desk, almost missing connecting flight for the 2nd time. Little to no communication as to why we were delayed. Very little help from flight crew as to what our options were since connection was missed etc.

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.

The entertainment portion was the biggest positive. Crew was pleasant and non invasive.

Not offering any sort of complimentary food on a 7 hour flight isn't ok. Not being transparent about not offering any sort of food is worse. Boarding was confusing with separate lines, scanning our tickets, herding us into a room, then directing us to go upstairs, then over a ramp, then into our plane without any sort of efficient zone boarding.

The entertainment selection was good (movies) and the staff was friendly, however on the 8 hour flight, my headphone jack to watch movies did not work.

The connector for my headphones did not work on the 8 hour flight, every other airline will provide, at a minimum, a complimentary snack where as on this flight you needed to pay for everything, seat assignments were changed (booked with a group of 6 and we were all sitting with each other when we booked it but when we got to the gate everyone was scattered. In fact, I heard a man say he was on his honeymoon and that they changed his wife's seat so they were unable to sit together.

Entertainment was not up to date or interesting. Flight attendant bumped me numerous times and no apology, I wasn't sticking out into the aisle. Boarding was delayed and not told why.

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,
