Alright, I've obviously been proven wrong! I stand corrected!

BTW, Brad, you mentioned that operating 4 737's would be more economical than 1 747.. That doesn't sound right. as someone
mentioned, you need more ramp space, more gates, more gate agents, more baggage handlers, 4 times the load on the IFR system
and the airports, 4 times the pilots, etc. etc. I dare suspect more fuel usage as well (aren't big a/c more fuel efficient as far as seat/mile)
I think as long as you can keep it full of passengers, 1 big a/c works better than many smaller a/c .

Also I was thinking how much wake turbulance does one 747 cause in comparison of 4 737s. As far as I know, a wide body makes 1.5 or
2 time the great wake turbulance than a small airliner (737 for instance). Therefore the controller has to leave a longer timegap after a wide
body, but still not as much as he/she should in the example of 4-5 small ones added up. If this is correct, then by the end of the day maybe
2 hours can vanish from the precious runway time...

Am I correct? What do you think?
