The original 737-100 and 200 were not big sellers for Boeing in the 1960s even in the USA. Western was renowned for going against the norm having not operated DC-3s or 727-100s so the 737 was in a way a natural fit and the airline's choices were limited after it was forced to cancel its ten orders for the One-eleven. As with the 720 the 737-200 would go on to be a major component of the fleet and unlike the former it was never replaced, except by more 737-200s (the Advanced model).
