Bratislava
Flew BTS-EDI on Wed evening (day trip 'fag run'). They seem to be building an extension to the terminal (looks about + 50%). Ours was the only flight showing that evening from the well appointed little terminal. Practically all 189 seats were occupied by what seemed to be nearly all Slavs travelling to Scotland.
By the way, FR sceptics, all three flights used that day (PIK - STN, STN - BTS & BTS - EDI) provided a very positive impression - even when there was a short delay in departure from STN, passengers were kept well informed.
Oh, and not forgetting the price, £1 + £1 + €1, with no added charges what so ever thank to a very easy to obtain Electron Card - acquired on line using the Bank of Scotland web-site
