Thanks, Green.
As I pointed out, IMHO this is a fascinating thread started by NGC - incisive and thoughtful with excellent research to corroborate.
Regarding passenger loads on the routes in question, pre-9/11:
I didn't work in airline marketing, I was in the Flight Operations side of a major airline (pilot). However, I do believe historical passenger
data is likely available thru DOT records...or even, possibly, old Annual Reports submitted by the Corporations themselves. (likely to be more
general, not specific).
The competitive nature of the airline business (what business isn't competiteve?) means, of course, many decisions must be played close to the chest.
This includes data of what are called 'advance bookings'. If a competing airline could discern what its rival is doing by observing equipment
swaps on a regular basis, it could be bad for business.
I do know there are a myriad of desicions about route markets that can appear contradictory on the surface, i.e. 'slot' allocations (usually related
to International), airport gate leasing arrangements, and, as I pointed out, the complexity of scheduling 500+ airplanes and 9,000+ pilots and 25,000?
flight attendants. Of course, on any given day, X number of airplanes are down for scheduled maintenance, Y number are scheduled to get to a facility
where they must conduct scheduled maintenance, due FAA deadlines. Naturally, the flight and cabin crewmembers have days off, vacations and, one other
contributing factor in the equation...Union work rules. Not to mention the FAA regulations that determine maximum times on duty...I will stop here.
Suffice to say, a major airline will not always have carte blanche to mess with their aircraft schedule ON AN HOURLY BASIS without serious downline
repercussions that can propogate into more serious service disruptions.
(one caveat to the above - unexpected weather or mechanical difficulties).
Whew! Didn't mean to go on so long, but sometimes a fuller explanation is useful for a fuller understading.
Thanks for the discussion.
