Right there with you! All the travelling does beat me down, and I sometimes find myself frustrated and irritable , but every once in a while you just pause under a warm sunrise in Sao Paulo, or a bitter night in Oslo, hear the noise of the APU, smell the burnt rubber/jet fuel of a fresh arrival.....and just realize how incredible it all is..........The you run around like an idiot for a while, and BOOM, another early departure with thrilled customers!!
