Pros: Cabin crew were very good. Very pleasant.

Cons: Unpacking wet clothes from one of my bags. It must have been left out in the rain for some time. I filed a separate complaint with Delta.

Good 7.3

Pros: The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot

Cons: We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate.

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,
please send us an and someone from our team will get back to you promptly.

^
The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
