Nothing notably. One would assume price but it wasn’t particularly different than non budget airlines. I didn’t know Norwegian was a budget airline until I got to my destination and was complaining about how bad my traveling experience was and they told me it wasn’t because Norwegian is a budget airline.

I had a backpack and duffel back for an 8 day trip overseas. I get this is a budget airline but Ryan Air works because the sacrifices make sense given the distances they travel aren’t hours. Shoving people on a flight like that with tight space, no food, no entertainment and charging me $65 for a duffel bag that you force me to check because I’m carrying 11 kilos in two small bags? Pass. Costing $50 less is far from worth it and I regret not opting for british or pretty much any other airline.

Cancelled after 4hours of waiting in the plane. Only one representative of the firm was outside and he lacked information. There was one hotline for all 300++ passengers to call, so of course everyone was on hold, yet this was the only possible means by which to get a flight transfer, because refunds, we were told, were not possible. Yet the next possible flight was (1) almost 24hours later, and nobody would tell us whether we would be reimbursed for an extra night's stay in accommodation and travel costs back into London , and (2) sold out within a few hours, so half the stranded passengers would have to get an even later flight, on Norwegian.

Cabin crew were friendly, efficient, courteous Refreshments generous and excellent. Good movies.

Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle.

Everything went okay for us on this flight. In the future, I will suggest to my wife, who books air travel for us to read the fine print. The cost to check a bag was $100.00 which would have run us $300.00 for the trip: Boston to Brussels with a layover in Reykjavik, but on the return Brussels to Reykjavik with four days in Iceland and the return to Boston, so there goes the cheap flight! I did enjoy the in-flight movie and a documentary on the return trip as well.

My own earphones on the flight from Brussels to Iceland did not work. I could not plug them into the system.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

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.
