Airlines are silly because they order the 777 over the "much more reliable A340?"

Let the facts speak for themselves:
- the 777 is MORE reliable than the A340 (99% as compared to 98.5%)
- the 777 has always been more reliable than the A340, ever since 1996, just a year after it entered service
- Sales figures, as of Sept. 2002:
777: 607 sold
A340: 325 sold (and the 777 entered the market after the A340)

So I suppose major 777 customers such as Singapore Airlines, Japan Airlines, United Airlines, British Airways, Air France, ANA, Malaysia Airlines, Cathay Pacific, KLM, American Airlines, and Emirates are "SILLY"? Seems to me that all of the ones I just cited above are large, successful airlines that know what they're doing when they ordered the 777. Singapore Airlines even ordered more 777's and are getting rid of their A343s because they are not meeting performance requirements. I highly doubt that a world-class airline like Singapore Airlines would make a "silly" decision.
