Anyone done it? Or work there

? Thinking of doing it Thrs or Fri (13th or 14th). Already talked to someone there who listed us on a Fri flight (standby) but looking at the weather it looks like it's supposed to be rainy and cloudy then.
Will call again tonight to see what it looks like tomorrow moring from Grand Canyon airport, said there were still some open seats then too.
Awesome deal, it's standby but $35 for the heli tours per person vs. something like $225-ish for the longer tour. Awesome benefit!
