A few months ago my friend and I heard that Norwegian Air was thinking about introducing low-fare flights between US and Europe. For example, NYC to Copenhagen or London. We read an article advertising prices at less than 200 American Dollars each way for a total of 400 American dollars round-trip!! Our jaws were obviously on the floor.
However, after some snooping around on the site I cannot seem to find any flight cheaper than 300 American Dollars one way so 600 total. This was done for three months in advance. We re-read the article and noticed that the advertised fare of 200 dollars was merely an introductory fare.
So our questions are: Will we ever see the 200 dollar fares again? Are there other budget airlines introducing routes within the next year? Can someone explain how introductory fares work?
