this is exactly how air travel works though. if your incoming flight is delayed you get delayed regardless of what the schedule says. setting a deadline does nothing to address the lack of a plane. the plane arrives when the plane arrives |

An airplane better arrive before running out of fuel. Somewhere, at least. That's a real deadline. You can't negotiate yourself out of that one. Empty tank == you will land NOW. One way or the other. So this is all full of safety margins, extra fuel, alternates, etc etc. But there is a time span which every flight will not exceed. Guaranteed. The pilots better be prepared for this, otherwise they die.
A flight is usually structured with many "lesser" deadlines. Latest time to abort takeoff. Latest time to turn to an alternate. Latest time for this-or-that to make for a safe landing. Glide slope. Localizer. The whole procedure to land a plane is full of deadlines. If you miss one, you execute a go around. Until you are out of fuel, then you better nail it.
So, no. Deadlines are not pointless. They can make the difference between living and not living.
