Flight was 2 hours late, causing a missed flight. Baggage took 90 minutes to arrive. The airline provided no info on connections as hundreds of passengers stood around for an hour and then chaos reigned as all rushed to get rebooked in only two lines. Nobody got rebooked until the next day and had to stay overnight in hotels with a voucher that provided only minimal food after a 15 minute walk to a fast food restaurant. the following day we were rebooked to Copenhagen rather than Berlin, with no guarantee of a connecting flight. I was forced to buy another ticket on another carrier in order to make my own wedding.

Flight cancelled due to overbooking, notification received while I was en route to the airport. Was assured I would be on the flight for the following day. Awoke next day and called airline to confirm, they stated my refund had been processed, I would not be on the flight, and there was nothing that they could do for me. I was forced to rent a car and take a completely different flight from another airport at a much higher price. Never again.

Boarding was well done.

Nice new plane seemed very spacious until the "herd" arrived then it seemed more crowded than I had expected. Staff was a it rigid, and NOTHING - and I do mean NOTHING is provided unless soupy for it. Well you can use the restroom. My sense is that Norwegian wants to pull you in with low prices- then somehow tries to get you to pay enormous amounts for food or services because you are a captive audience. So I am not impressed and would have to say that other airlines are better. I think with a proper strategy you can make Norwegian Air work.

Newer planes but don't be fooled. Unless you Pay Premium fare, be prepared to be "nickled and dimed" to death and pretty much treated like second class citizens. I fly several times a year and this was my worst flying experience to date. The new planes and fancy entertainment on seat backs doesn't make up for the crowded seating and poor service/treatment

Paid extra to pick seats. Not to pick a better seat but to pick any seat ahead of time-like a lot extra! Paid extra for food- you get nothing to eat or drink- not even water- unless you pay. If you don't pay for food, the crew ignores you. Paid extra for baggage-Sizes/weighs allowed for baggage is less than American air carriers

They kept me and my two year old in the plane for almost 4 hours and told us that we will take off every ten minutes, but obviously we never did. We got rebooked for the following day. They provided a small room to stay in and $7 wach for food. They treated us like a huge inconvenience. We had to pay for food, my husband had to take another day off work to come get us. This airline is shameless. We are spending more money to with a different air line next time.

The 787 Aircraft was nice.

3+ hours of delay on a 6 hour flight isn't acceptable (DY7148 from Boston to LGW on Jan 7 2018). After late arrival of the aircraft, "weather" caused a 1 hour delay in boarding and another hour of delay for loading bags. The only "weather" in Boston was "cold" (aka winter). Perhaps they'd have to cancel the flight if someone saw a snowflake.

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.
