I fly routinely for work including internationally. I have always been able to carry on 2 pieces of hand luggage -- 1 small rolling bag and a personal messenger bag. I was surprised upon my return flight to be told I had to check one of my bags because their combined weight > 10kg. There was no problem with me having both bags for carryon during my departing flight. The return flight wasn't even half full, so there was plenty of cabin space for my rolling bag. Instead, this was a ridiculous policy of Norwegian so that they could ring some money out of me. I doubt I will fly with them again.

Nice, clean plane.

1. Flight attendants except for a couple, were not interested in helping passengers or answering questions 2. For the basic fare (which I didn’t realise I was even purchasing), you had to pay extra for a seat and for luggage, on long haul transatlantic! 3. I wasn’t offered food or beverage once on the 8 hour trip 4. You had to purchase a blanket if you wanted one. Everyone was wearing their coats onboard. It almost felt like they were intentionally keeping the temperature cold to induce passengers to purchase blankets. When I requested they raise the temperature, I was told that this was the warmest they could make it and this is the warmest on any plane. (Obviously not true. I fly every month and have mostly found plane temperatures to be manageable.) Oh, and did I mention how you had to pay to check luggage on a transatlantic flight!!

This flight was miserable. Seriously, one of the worst flight experiences I've ever had. The leg room was absurdly small. I'm not a tall person and I only had one inch in front of my legs. When the guy in front of me put his seat back it pressed into my knees. There wasn't enough space to bend down and untie my shoes, let alone get something out of my bag. My shoulder and knee were touching the guy next to me (a complete stranger) for the entire flight and there was nothing I could do about it. This was a red-eye but I absolutely could not sleep because it was so uncomfortable, so when we landed I had a terrible migraine and was nauseous and disoriented going through customs. I actually had to sit down in the airport because I though I was gonna pass out while trying to carry my bag, that's how shitty I felt after this flight. On top of that, not being able to sleep on the flight really messed up my sleep schedule and so jet lag from the time change has been made even worse, so I'm completely out of whack and its so much worse that it otherwise would have been because of the horrible flight. Also the food was gross and there wasn't enough of it. Even now, I don't think I have really communicated just how shitty this flight was. I was actually angry when I saw my seat upon boarding, and I'm still angry about it now.

I like how quick and efficient the boarding and check in process was.

I just wish that if I paid a little more for seats I should get more comfortable and roomier seats is all. Don’t make the seats sit so upright.

I liked the movie selection, that the seats reclined and the staff and food.

There where four flights all due to take off at 1030 with this company which caused major back up and delay in check in and tsa. They did not delay the boarding times and I had to run to get my plane even though I was at the airport 3 hours before hand. I barely made it running full force in my sock feet. I was very disappointed being a first time customer with this company.

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.
