I waited in the airport for 6 hours before learning that my flight was cancelled, and had to rebook... I was flying to New York to see my family, so I didn't really have any alternate transportation options!
That's a shame, sorry to hear that. I got more lucky: I had to wait for 6 hours too but my flight suddenly resumed (must have been one of the first few). I didn't have any alternatives to go home either so I feel for all of those stuck in a foreign country.
