Marie,
This reminds me of what happened last year with a computer glitch in Icelandair. People were buying tickets from the US to Reykjavik, Iceland for $30-$50(maybe even less!) in the summer months! I followed the thread in Flyertalk.com with interest as all these people reported in their spur of the moment purchases. It was hilarious! Too bad it happened before I had to purchase my tickets to Iceland for this summer :( !
