Certainly if the crew hotel is under fire than there is not choice other than to cancel flights. However, if the hotel your crew stays in is not involved than I really don't see an issue.
And yes, it's easy to talk "big" until you're under fire. But that's just my point. The terrorist event is over. There is no fire.
Imagine if airlines pulled out of Tel-Aviv every time there was a terrorist event.
I don't fault Delta for doing what they have to given the circumstances, but at the same time I don't think it's reckless for CAL, BA, Swiss, or any other airline to resume service.
Not quite true. Part of the terrorist group was not caught or killed...
