It can still reduce prices (and open availability) on flights that are relevant to most people on this forum.
So should we hope, fantasize, or encourage some kind of activity, in order to make those relevant issues happen?
Will other yidden be mechalel Shabbos for any of the possible benefits to occur for shomrei Shabbos?
IMHO the only reason to care about these flights is if it bothers us more that yidden are mechalel Shabbos, and we can do anything to counter that (by increasing our own shmiras Shabbos, or by trying to educate others and help increase shmiras Shabbos).
