Well, that's how it starts!!! I was upgraded on NW a few times when I was silver from MSP all the way to BKK, it was just awesome, then you find how hard it is to travel in Y, and then you start trying to find "reasonable" biz fares, and you get hooked deeper and deeper until you only can imagine flying in biz on anything longer than a 1 hour flight, and then you get upgraded to 1st (on Emirates) and realize just how darn nice it is to take a shower in flight and then you start looking for "reasonable" First class seats, and find the feeling of how it is to be a movie star on a set, you just check-in and somebody is golf-carting or escorting you everywhere (on Thai for example) and you realize that you have to go back down to biz, but you don't want to and then you are so sucked into the happy air life that you can't imagine where all those people at your baggage claim came from since you only saw about 30 people on the plane in biz or first, and the way they dress, LOL, .... I'm just saying...
