” to do so would be to make a huge kiddush Hashem – imagine the effect of a bunch of yidden doing something like that… “
I have seen many people make this tayna, but I don’t think there is much Kiddush Hashem invilved here, there were hundreds, if not thousadns of people who booked a whole bunch of flights for themselves, fmaily, friends, etc knowing that they can check scheduling, etc later and then cancel within 24 hours any “extra” flights. So I’m sure there were many cancellations today but the companies only see that as people cancelling flights that they were never planning on taking rather than people cancelling because it is “the right thing to do”
