Mags, the airlines are "public transportation", in that they are how the public fly. Similar to the bus is how people with no vehicle get around.
Now, I understand your plight as a multi-flight traveler. The thing is.......it's very hard to sympathize with you. You see, you sound exactly like the guys I see, and hate, in every airport I've ever been in.
You feel that since you fly "more than most", it should garner you some exclusivity. A lot of this comes from a certain familiararity with the proccess of flying, I am sure. Like anything in life, when you are more adroit at it, the "newbies" or once-in-a-while folks tend to raise the blood pressure a bit. If you golf, you don't want the Sunday hacker in front of you all day. If you're at the checkout, you don't want the person grabbing their checkbook and starting the check AFTER they are told the final total. Things like that. As a regular flier, you have it all down cold. Most don't.
Sure, you add the ill-mannered in there on the plane, and that doesn't help. But the thing for me? The "business traveler" has always seemed to be the biggest prick of all time in the airport when it comes to manners! And by appearance, it seems to go back to the attitude that you seem to have on the subject:
You guys think the airport, and the planes, are yours.......everyone else is intruding on your space!
Yeah, I hate the loud kid in the atrium while I'm eating that $11 cold sandwich. Parents oblivious to his playing, while other people cast their stares. But, I hate even more the businessman yaking into his Blackberry loudly 18" to my left while I'm in the same setting.
Yeah, I hate kids running around past me while I'm heading from one gate to the next, and maybe bumping into me. Even more so, I hate when Bluetooth is running past me with a multi-decker carry-on on wheels, and rolls over me, and three other people, but doesn't miss a beat in his conversation.
But, I'm sure at some point he'll interupt his own phone call to mention all the goddamned kids running around his airport.
So, you are right. If everyone took care of their own laundry......no one would have an issue.
