wrt flight cancelations, etc. > I'm not even sure who makes that call: is it the pilots, or someone in a central office somewhere? The relevant regulation is here, https://www.law.cornell.edu/cfr/text/14/121.533 https://www.law.cornell.edu/cfr/text/14/121.533 The "operational control" is jointly shared between the pilot in command and the aircraft dispatcher. In theory, either one can cancel the flight. In practice the dispatcher does it or a shift duty manager (who may not be actually performing dispatch duties) who is the "man behind the curtain" and oversees all flight operations during their dirty duty shift. Big carriers may have several managers, assigned per region (CONUS, Asia Pacific, Europe-Trans Atlantic, etc.) but the theory is the same. [me: licensed dispatcher & former flight ops duty manager]
