Both Austrian Airlines and Lufthansa announced today promotional flights to North America. The promotions are almost the same. As they are both valid for flights from October to mid Deceber and Jannaury to mid March. The flight prices are very similar, being the base price of Lufhtansa slightly cheaper than the one of Austrian Airlines. However, we strongly advice you to check them both as the cheapest seats sell fast.
Some example of prices offered are: Washington (around 4000 kroner), New York (3800 with Lufthansa and 4200 with Austrian), Toronto (around 4600 kroner) and Las Vegas (4800 kroner).
Besides that, it is worth to mention that Norwegian announced local flights in Norway for around 350 kroner each way. In the other hand, SAS has announced local flights for around 499 kroner, but with a special offer where the kids travel for free (just paying the taxes).
