Use ASIC for upgrade?
I've heard rumours that flashing your ASIC at check in on a commercial flight might get you an upgrade of some sort.
I'm a PPL (so not employed by an airline if that makes any difference to the answer) who's planning to go overseas in a few weeks. Is it worth shoving my ASIC in my handbag and pulling it out at check in (and then putting it away again, I'm not planning to wear it around the airport)? Or is this all just a rumour?
