Absolutely true, that's what the official press release of PRG says:
Prague, 8/31/2009
Starting tomorrow, September 1, services will cease being provided for SkyEurope until such time as regular agreed prepayments are reinitiated. If cash is delivered during the course of the day tomorrow, our company is prepared to immediately reinitiated provision of services up to the amount of the deposit paid.
Until the present, Prague Airport has provided comprehensive services for SkyEurope connected to the processing of aircraft and passengers.
Passengers whose SkyEurope flights to not take place are recommended to contact their contract partner at SkyEurope Airlines, or use the information hotline: 296 096 096.
Well, unless SkyEurope is a contemporary embodiment of a mythological Hydra (well,
Greek anyway), the chances of survival must be very weak indeed.
