Well, the good news is that I made it on time (early even) to Tel Aviv. But SFO was a total mess in the storm. I was on CO 449 and, as ContinentalFan indicated, we left super late. The CO agents in San Francisco were smart though - they put all the TLV bound passengers on CO 449 (all 34 of us) so as to increase the chances that they'd wait for us in EWR. They pulled the plane into the neighboring gate and we rushed off and onto CO 90, TLV bound, and they closed the door right behind us. Alls well that ends well, but I feel really lucky (and grateful - all the CO agents were great all the way through).
