I was speaking more generally, not about flights specifically, and about how common it is.
Adults throughout my life seem to constantly be rushing to everything. As a proper big boy adult now myself (I'm almost 40) I still don't get how it's so pervasive. My comment was more about how common it is, not about reasons people might be in a rush. I can think of plenty of reasons any given person might be in a rush on a given day but so many people seem to be in a perpetual mad dash. That bit boggles my mind.
