I help everyone I can, all the time. If someone looks lost, I stop and help out. If granny needs help with her bags or can't find the gate, I make sure she's sorted out. If Soccer Mom is worried about her connect, I take the two minutes to read her ticket, lok at the delay, and give her viable options. I know it's not my job, but that's not the point. I do it because it makes me feel good, and because it improves the public opinion of our industry.
Let's face it, people hate the airport because it's a big, stressful, confusing, frustrating mess. Thanks to movies and TV, they think pilots are bumbling philandering alcoholics (Yeah, I know, we are. But still, I can fake the funk on the nasty dunk can't I?). So if I can kill three birds with one stone, namely, making one or two persons trips more comfortable or less stressful, improving thier opinion of our profession, and getting a little karmic buzz on the side, then what's the harm? We all win!
I have a dark side to all this-- it's making the gate agents look bad. I hate gate agents. They are the spawn of Satan. If I can get a whole planeload of people to love me and hate them, then I am happy. Anyone who has had to commute understands this.
There is a special level of hell reserved for thieves, liars, Scientologists, and gate agents.
