850 people X how many minutes each to get off and on ?
it does not end there. 850 people with needs for taxis, rental cars, and parking for people who are there to pick them up.
850 people going onto the surrounding roads and highways.
(not to mention bathroom facilities)
Now add all the other flights comming and going.
i really think the cost per passenger mile will make the final decision.
The future is in the RJs and the Beyond-Regional-Mini-Jets.
