Don't get me wrong. I have NOTHING against Wroclaw, been there, everything OK! But this is a classic example of... well, an idiotic decision. Calling everybody idiots? Look in the mirror! There exists a similar route by Wizzair. Three times a week from TRP to WRO. Take a look at the flight prices in January:
Tue 05 Jan..... 89 NOK
Thu 07 Jan .... 89 NOK
Sat 09 Jan .... 89 NOK
These are total prices, all taxes and fees included. 9 euros (8.50£) per flight. Now what's the point in that? With so meagre popular interest so far, after FR starts the route the price will drop to 0,01 euros or so. If Wizz resign, Ryanair will likely follow and after a period of daily flights there will be no more flights at all. A totally pointless fight there.
Some research would show the price of cheapest tickets between Finland (anywhere) to Norway (anywhere). In January, unable to find any return flight below 200 euros.
Where's the logic?
