Hi. I have a quick question. I see airlines which start out with a small fleet, such as WestPAC, and start number at say 900 (i.e. N901WP). Why do they do this? Is there any perticular order airlines do there registration numbers?

no, not really. Each airline has its own system. CO uses straight numbers whenever possibe. ex N77303. The first 2 no's are not important, but the final three designate the aircraft, for CO, 3=737-300, and the ship no(03). Sometimes, numbers simply run out and have to be reused. AA's 767 registrations were once crried by their DC-7s. Today, AA's 757 fleet now numbers more than 100, so 601-699 are used, and then 181-184. The MD80 fleet covers the 200s,400s, and 500s!
