LAS recently moved to the #5 spot in the US in number of passengers - is that what they meant?

According to the McCarran airport website, UA had 1,113,562 arriving and departing passengers YTD in 2006 through April (5% increase over last year). Anyone have any idea how that compares to other UA stations. I have to imagine ORD, DEN, LAX, IAD, SFO are all higher numbers since they are the hubs. Could LAS be bigger than one of those airports?

Interesting....
