I'm guessing you have no idea what airlines do concerning "these issues" and adhere to the strange idea that anything short of a perfect performance proves malfeasance on the part of the airlines.
These events are rare, which is amazing considering that airlines are attempting to run all-weather, reliable hubs. What most airlines do now (as Boyd says) is cancel flights in anticipation of ice events. Delta famously did that when the Super Bowl was in Atlanta. The forecast missed and several thousand fans had to do marathon drives in perfect weather to get to the game, or missed it.
It's never going to be perfect. It can't be legislated to be perfect. It's strictly political preening.
You seem very confused. Neither I or anybody who is pushing for a passengers bill of rights thinks it's going to produce perfect performance. What it will do is provide for a specific penalty for wildy under-performing. Nobody is entitled to compensation for being 30 minutes late. Being held on an outbound aircraft 10 hours, being held on a diverted aircraft 8 hours or as was recently done abandoning passengers in Nebraska without any communication on what to do next, are all things that if an airline was financially motivated to mitigate those circumstances they certainly could.
For example, let's say 3 hours sitting on the tarmac at JFK is a reasonable amout of time to wait in blinding ice storm trying to depart, if it's not going to happen in 3 hours and there was a financial incentive to get the people off hell yes JetBlue would have found a gate.
Yes it's a rare occurence. So is pre-meditated homicide resulting in the death penalty, but we're perfectly happy legislating that, there's no good reason not to legislate this. Because - CLEARLY - the airlines cannot self-regulate on this issue.
