The flight attendants were very kind and hoped to make up for the pilot’s negligence.

Boarding was weird with a lack of overhead bins and then the pilot was inconsistent with updates to safety issues. We were delayed by an hour and twenty mins and then had to wait on the tarmac for another plane to leave the gate. Feels like I wasted two hours in limbo.

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.

The ticket price was amazing. It made the negatives acceptable. Friendly but scarce attendants. Although there was no electronic boarding pass for my phone, the printed one did contain useful information.

I was unable to find out how the $9 Club could save on baggage fees. No answer from online help. I thought baggage fee would be in line with American. But NO it was twice as expensive. Next time I will wear camping clothes and pack everything in my personal carry on. Web site is difficult to navigate.

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.

There were many delays and cancellations due to bad thunderstorms at LGA. Despite a few hours delayed (because the airport was closed due to the storm), the flight was still schedule to leave! I was very happy about that. They did issue waivers for those who could not make the later time. Once delta got the ok to fly.. The flight left the gate very fast and we arrived and exited the plane super fast too. The process was so efficient and quick, I did not feel the waiting period. The flight attendance were so happy and positive, they made he flight very enjoyable. Great job delta!

Although we ended up being stuck on the plane for 2 hours prior to take off due to high volume, weather and as the pilot put it, "possible military activity" the crew kept us informed every step of the way. There was one flight attendant in particular who was so full of energy and made the unfortunate circumstances not so bad. She entertained us and kept us in the loop the entire time as did the pilots. It made the 2 hours not feel so bad which was appreciated.

That we were delayed on the plane for two hours on a small plane but I know it was out of their control.

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,
