My wife is Slovak (and we often fly Skyeurope from LTN to Kosice/Poprad). One of her friends is a SE cabin crew and she told us last week that staff have only been paid 1/8 of their salary for the last 3 months. They are closing the Kosice office, relocating staff to Bratislava. In the next month or so the flights to Poprad from LTN are likely to be be scrapped. They are however expecting their new (!?) planes in by the end of March, apparently from an ex Soviet country and a big improvement on what they have been using lately.
She thinks the company will survive until at least the summer, but after that there is a huge question mark.
