Appears there's no SEN - KRK either from 14 September 2014, all other routes except those in question are now on sale until 25th October.
From 15th September that leaves only: Alicante, Amsterdam, Barcelona, Berlin, Faro, Geneva, Ibiza, Jersey, Malaga, Palma and Venice.
Appears also only 3 aircraft again at this time (might explain AMS reduction) but I'm sure could quite easily go back up to 4 by Summer 2015.
