The last time we flew Delta, we were underwhelmed. Our flight was delayed several hours and there was nothing exceptional about it when it did finally leave. That was 5 years ago, and there's been a lot of changes. There I'd now in-flight entertainment, reasonably comfortable seats, and everything was on time.

Virtually no food options.

Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations

The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes.

Fast boarding.

The flight was half empty and when I tried to move a row ahead of me (from economy to economy plus), the flight attendance rudely told me I had to move back to my seat since the economy plus seat was $70 more. However, a reasonable airline would upgrade their customers to first or economy plus to not only appease their customers but to fill some empty seats. Therefore, I had to spend the entirety of my redeye flights crammed next to someone while I was looking at an almost empty economy plus section. Also, we boarded earlier than expected but we spend an extra hour on the flight waiting to take off. I would not have minded boarding early if we had taken off early, but we took off an hour later.

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.

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.
