well your statement shows how much you don't know about this company....who cares if it worth more than all the US airlines?!? as over 80% of its revenue comes from hotel bookings, and over 81% of its revenue comes from outside the US, so why would you even compare it to the value of all US airlines....don't short stocks you don't understand
They make more money/share than all our airlines combined also. Wait, what's your argument,that the airlines are overpriced or that priceline is? Those airlines especially the new AA should figure out how to leverage buy pcln and kept it independent but keep every AA plane full!!
