The crew was really nice.

So many delays. My flight was eventually cancelled on Friday and was rescheduled for Saturday. The Saturday flight was delayed. All in all, i wasted a vacation day on Friday, I paid for a hotel in Denver for Friday night that I was not able to get refunded, I missed out on a day in Denver. It was a huge bummer.

Gate crew didn't help much with seating or connecting flights. Staff almost never smiled, and when boarding the plane instead of a, "hello" or "good morning", there were two attendants staring at their phones. They looked up when I greeted first, but seemed put off a touch. They also switched the seating without telling us ahead of time, so my husband and I had to sit in middle seats, apart from each other on our anniversary trip. Very unhelpful and unfriendly when I inquired to change.

Delta staff taking care of rude/beligerant guests first vedore guests patiently/kindly waiting in line ... children watched that behavior and the jerks recieved special treatment. Flight staff ripped up guests boarding pass in face. Staff allowed ys to board plane and put our bags under plane and then crew timed out before take off. Never will use Delta again.

Our original flight was delayed and Marika, at the Delta gate of another flight to the same city, was able to get us on the flight that was going to our city. We were so grateful to get home before the winter storm! We appreciate your staff and the help their quick, efficient manner to get us on a new flight!

The dirt cheap, I can't believe an airline can operate at this low an airfare and still turn a profit-ticket prices

The hidden checked-baggage fees that were almost half the cost of the actual ticket for one bag. The non reclining seats. The lack of legroom. The feeling of cattle being herded into a slaughterhouse. The lack of friendliness with the RDU and MCO gate/ticket counter agents. The cost of having to pay $12 to ensure I sit beside my 5 year old son on the flight. Besides a free seat belt, having to pay for everything else under the sun. Surprised AC was free. Not even an in-flight magazine or barf bag. Which is exactly what I feel like doing after giving you my money......

The crew was very friendly.

The seats were close together and not very comfortable. No entertainment, for example a movie for a 4 hour flight. You have to pay for everything. Only thing complimentary is water.

Cramped seatting, minimal food or beverage options and we were invited to provide our own entertainment. Pretty typical flight for ten or fifteen years ago. The crew was extremely pleasant. Very surprising and maybe the only saving grace.

The airline is clearly trying to maximize profits by squeezing any comfort from the plane while still charging ludicrous amounts. Good for them. That's their free market choice. But do not then be startled that everyone is angry before, during, and after your flights. In the long run that's how you shed customers.

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.
