What would you consider to be the more important number, if you were to invest your hard-earned money into a company's stock? The number of units sold or the total value of those units sold?
This paragraph pretty much sums it up: Boeing has more potential revenue on the table than Airbus, period. I mean, who cares how many airplanes were sold; what I want to know is how much money are you going to make on your product.
That's because a large fraction of these sales are the planes that are the lucrative moneymakers: the 777 and 787. These two planes will replace a large number of older widebody jets in long-range service; is it small wonder why Airbus is scrambling to catch up with the A350 program?
