It's funny noticing other pilot reactions as you're about to pass them in the terminals. They're thinking, Is he looking at me? If he does, do I nod, smile, or tip my head? Then, some act like they don't even see you and look straight ahead without a blink. But, oh, they know you're there alright
In the past Delta pilots were the ones with their noses in the air, but I've noticed recently they're no diff from our Southwest friends. The shared difficulties these past years have leveled a lot of high ego's.
