It is of course possible that the Donald overturns the DoT, I personally think it's unlikely, the DoT despite 3 years deliberating over NAI application could not find any cause to reject it and it was the threat of arbitration that moved them to approve. It is worth remembering that even if Donald was to decide that Norwegian a large buyer of Boeing aircraft was more important than China,Russia, banning Muslims, building a wall with Mexico and so on, it changes nothing, Norwegian have the rights under their open skies deal with Europe to fly to the states, it just makes it a bit more messy for them, that's all AND if the D did overturn the approval it just takes us back to where we were a few weeks back.
The EU would seek arbitration, even if that went against Norwegian still nothing changes, although the EU would then seek redress starting with a recipical ban on a US airline none of which is likely, while all of this will no doubt bring glee to the detractors it changes absolutely nothing.
I would ask DB & co just what changes they would like to see, for me it would be direct employment, forget flying on a Norwegian national contract, the business model won't work, if Ryanair said tomorrow that they were starting long haul on their Irish AOC nobody would blink an eyelid, Ireland does not have less safety oversight than Norway, the labour laws might more business friendly, so what, that's true of many countries that fly to the US, what employment protection do EK crews have? In fact it's only in socialist Europe & the US that these rights exsist
Let's see what the Donald does once he's sworn in, he won't be interested in the US unions who bank rolled Hillary.
Norwegian have a fleet of 120 Boeing aircraft with hundreds more on order, by the end of 2017 the long haul fleet will number 21 787's alone
