Actually while booking there was the 'insurance' part to choose it (with an additional extra cost) but I removed it since a colleague told me it's not necessary to have it (like as well the selection of the seats in the plane with extra cost) since all these it's a way for them to gain money.
I can add though now that insurance retrieving my reservation online. Do u think that if that insurance part is not paid then I'm completely 'uncovered'?
But why then to give them more money if anyway when my flight is cancelled they will not refund anything.
It's their responsibility though according to the rules to arrange you to the next possible flight by them.

#10 is new to me. Any source? They are a prosperous airline, introducing new destinations and expanding their fleet. As I know them for 5 years.

#11 I wonder if that insurance is for case of bankruptcy. Read through their 'Terms & Conditions'. Under normal circumstances they did rebook automatically or gave you some kind of refund (eg. voucher), so you are 'covered'. Your question is about an other case what I'm not really familiar with (luckily).
Packa re #12. I have no direct source but i've read about it on a reputed Belgian aviation site:

An entry by one person in a board is certainly not much of a proof about the economical situation of a company. Is the user "secondlife" more trustworthy than the other ones who doubt this?
The poor economical situation of SkyEurope was addressed some time ago in the economy news sections of established newspapers/magazines.

#14 OK, thanks. I don't see if it was serious then. For now it seems to be nothing more than a gossip. But these whispers can corrode the reputation and trust and finally lead to the situation what they are about (see the the financial crisis). As always, there are a loads of competitors awaiting for this to happen. Or not just waiting, but doing.
I don't think the link I gave in #4 could be counted as "nothing more than gossip", do you? SkyEurope has gone into administration. That isn't gossip, it's fact.
I've been away for a few days.
Tony, #15 and 16 both were reactions on my #10 and 14, not on your #4.
I should apologise for having posted a statement which was not based on a more trustworthy source.
Even though i know that the forum i've referred to is known as a very serious and reliable one, abalada and packa are right to interpret my statement in #10 as a gossip.
That's why i have asked the mods to remove my reply.
Sorry again, i have reported myself :)

Okay folks, here it is straight from the horse's mouth. Just had my wonderful experience with Sky Europe on August 15th. We flew from Paris to Prague on August 12th and had no problems whatsoever, but for our return trip on the 15th, we were forced to spend 7 lovely hours in the Prague airport because, apparently, the Paris airport had seized one of SE's planes for non payment of fees. SE then decided to try and do a four plane route with 3 airplanes. This caused major backups throughout the entire system. According to the Czech girl I was sitting next to, this kind of thing has been happening rather frequently these days as she said the same thing happened to her for her flight from Paris to Prague. Word the other day was that Vienna had also seized a SE plane for non payment of fees. For our troubles, SE gave us each two $10 food coupons to use in the airport.
I would say anyone with a current ticket to fly on SE right now is basically playing Russian Roulette with their travel plans. You may get to where you're going or you may endure a 7 hour delay like we did.
Good luck, but I'll never book with them again. Give me Ryan Air or Easy Jet any day.
