As I sit here on an overly hot aircraft, 35 minutes into a ground delay because of all things...the air conditioning, a thought comes to mind; why can't pilots, or for that matter, gate agents, tell the truth about delays? Why is it always the standard "10-15 minutes" when we all know that is nothing more than BS used to placate the pax? If it is going to be an hour....tell us for heavens sake! We are adults! We can accept the truth! Well, most of us can!!!! STOP THE LIES!!!!!
