Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this.

Flight was fine.

My one complaint is the bathroom layout of the A320. Two tiny closet bathrooms in the back for all of coach and a much larger one much larger one first class (which is like 5 rows with a mesh curtain for separation). The coach bathrooms are so small a normal person can barely get in and turn around to close the door. I question whether a larger person would be able to actually use them. I also saw the flight attendant actively turn away coach passengers trying to use the first class bathroom when it was open (not standing in the aisle or anything annoying like that). That's ridiculous to have 2 tiny bathrooms for all of coach and also to make people walk all the way to the back of the plane when you are seated much closer to the first class bathroom.

Boarding was fine. And service was good.

TV controls didn’t work. So I couldn’t watch anything for the 4+ hour flight.

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,
