Europe's best low cost airline is invading America and US rivals should be afraid

Norwegian Air has been named best low-cost airline in Europe for the fourth consecutive year by leading consumer aviation website Skytrax.

In addition, the airline also took home the prize for best long-haul low cost airline in the world.

Norwegian was presented with the awards at a ceremony on Tuesday during at the 2016 Farnborough Air Show.

"We believe that not only should air travel be affordable to all, but also that low-cost can still mean high-quality," Norwegian CEO Bjørn Kjos said in a statement.

"These awards give us huge momentum as we continue our ambitious expansion plans in Europe, the US and beyond."

And Norwegian is certainly making their presence felt.

The company's Norwegian Air International subsidiary's expansion into the US has ruffled feathers. It's a potentially industry-changing move that US airlines and unions have vigorously opposed.

The US airlines are objecting on the grounds that NAI could exploit foreign labor laws, but in truth they should be worried about the kind of international network the carrier is attempting to create.

In April, the US Department of Transportation tentatively approved the Irish - yes, Irish - airline's application to fly into the US.

You may be wondering why an airline called "Norwegian" would be based in Ireland. That's the root of the issue.

NAI is one of several subsidiaries operating under the Norwegian banner. Unlike the rest of the company, including Norwegian Air Shuttle, NAI is based in Dublin instead of in Norway.

This, critics say, allows NAI to take advantage of Ireland's employment laws, which are significantly less stringent than Norway's. As a result, they say, NAI could hire lower-cost pilots and cabin crew members from Asia to fly trans-Atlantic routes. (The company claims its current service to the US is operated by NAS with Europe-based crews.)

AFL-CIO Transportation president Edward Wytkind referred to the DOT's decision as one to "green-light this low-road air carrier whose operating plan will destroy fair competition and extinguish middle-class airline jobs here and in Europe."

But NAI says none of its Asia-based crews will operate flights into and out of the US. Further, the pay differential between the airline's Asia- and Europe-based pilots is roughly 1%, Norwegian Air spokesman Anders Lindstrom told Business Insider.

And all this complaining about NAI is happening even though it is tiny, with a fleet of just 10 Boeing 787 Dreamliners. The major US airlines and their European alliance partners have more than 1,000 wide-body long-haul jets at their disposal and are responsible for more than 80% of the traffic across the Atlantic.

Here's why Norwegian is scary

Here's the real problem for US airlines: Norwegian is going to expand rapidly and in a way that eats at the foundation of the hub-based system major US airlines depend on for survival.

How? By offering direct flights to smaller cities in the US from underserved cities in Northern Europe.

In practice, this means passengers in Hartford, Connecticut, or Providence, Rhode Island, no longer have to fly to Boston or New York for an international trip. Instead, for a far lower cost than a US carrier, they might fly NAI to Oslo, Norway; Stockholm; or Hamburg, Germany. Later this year, Norwegian is launching service to Paris from New York, Los Angeles, and Fort Lauderdale.

This kind of setup not only undercuts US airlines' international business; it could also threaten their domestic operation.

But there's more

With its base in European Union-member Ireland, NAI will also be able to use its hubs in Europe as transit points for passengers traveling into and out of Asia and Europe to the US. As a result, NAI will be able to tap into the lucrative US-to-South Asia market over which US, European, and Middle Eastern airlines have fought for the past decade.

The presence of Norwegian and its low-cost model could provide competitive pressure on legacy carriers for value-minded travelers the same way Emirates, Etihad, and Qatar have for premium-cabin clients.

In fact, NAI could be the airline to disrupt the trans-Atlantic long-haul business the same way other low-cost carriers have transformed the European airline industry. In Norwegian's home market, it has forced its local rival SAS to revamp the way the 70-year-old airline does business.

"We have made significant transformative changes to stay competitive and to survive," SAS CEO Rickard Gustafson told Business Insider in March. "We have cut overhead costs, adjusted pensions and union contracts."

NAI's weapon in all this will be narrow-body jets like the Boeing 737 Max 8 and the Airbus A320neo. The company has orders for as many as 350 of these aircraft in place.

While trans-Atlantic service has traditionally been operated using large wide-body jumbo jets, the narrow-body jets are cheaper to buy and cheaper to operate. The first of the 737 Max aircraft are expected to enter service in 2017, while Norwegian is expected to see its first A320neos later this year.

Norwegian won't be able to reach the US legacy carriers' bread-and-butter customer: the high-end business traveler. Major US airlines depend these high-value clients, who fly often and pay full-business or first-class prices, to generate the revenue they need to stay afloat.

Norwegian's low-cost premium cabin on its Dreamliners may attract some of these customers, but it is unlikely to sway high-end corporate clients.

But based on how Norwegian has shaken up the airline industry in its homeland, US carriers should be wary of the disruptive power of this airline.

One final detail: According to Norwegian's CEO, the target price of admission for one of his airline's flight across the Atlantic is $69.
