US airlines are freaking out about a company you've never heard of

The US Department of Transportation made a potentially industry-changing decision when it tentatively approved Norwegian Air International's application this month to fly into the US.

It's a move that has been vehemently opposed by US airlines and unions for several years.

They have argued that allowing NAI, one of the several entities operating under the Norwegian Air umbrella, into the US market could jeopardize the health of the US airline industry and its workers.

The issue lies with where Norwegian has chosen to headquarter its NAI subsidiary. Unlike the rest of the company — including Norwegian Air Shuttle — NAI is based in Dublin instead of in Norway.

This, critics say, allows Norwegian Air 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 from Asia to fly trans-Atlantic routes.

The alarm among US carriers is overblown.

With just 100 aircraft, Norwegian Air loses money and accounts for a tiny fraction of travel between Europe and the US. And its no-frills, low-cost model works best with smaller aircraft, rather than the Boeing 787 Dreamliners and other large aircraft needed to fly across the Atlantic.

It's why Norwegian can compete so well flying Boeing 737s in Europe but can't make a profit on its trans-Atlantic flights. Other attempts at low-cost travel across the Atlantic have ended badly. Remember Laker Airways Skytrain or People Express? There's a reason you don't.

'Not a fair market'

So why is there so much acrimony over the DOT's decision? In part, its just the notion that an airline can choose a home base only to take advantage of labor laws that allow it to undercut its competitors.

The US-based Delta, United, and American airlines can't just pick up and move in response.

"Norwegian Air International has picked its place of incorporation based on whether that nation's tax and regulatory laws are favorable," airline pilots union president Capt. Tim Canoll said in a statement.

"As a result, NAI gains an enormous competitive advantage over US airlines, which are required to do business under one set of US laws and regulations. This is not a fair market."

Norwegian Air Shuttle is currently operating trans-Atlantic flights with European flight crews and the airline says it has no intention of hiring low-cost crews from Asia.

Norwegian Air spokesperson Anders Lindström told Business Insider that the airline has told the DOT that it will not be using any Asia-based flight attendants on its trans-Atlantic routes.
