One question that strikes me a little..:
Brief review of History of Aviation Economics:
1.) Prime Strategy was point-to-point demand
2.) 80-90s: Enhancement of Hub-and-Spoke operations
3.) Thereafter: Alliance networks
See also this wonderful paper by Yergin, Vietor et al:
Now, do you also think that with the induction of ULR Jets, the point-to-point strategy is reinvigorating (i.e. campaigns like NY - SIN in 18 hrs, focus on non-stops instead of hub-operations etc)? Of course, the one does not exclude the other - however, I somehow have the impression that ULRs could lead to the enhancement of routes that primarily target O&D instead of 6th freedom pax.. Personally I believe that ULRs will not really be that successful in the future (I might well be wrong), as long they do not reach the supersonic speed... but that is only a sidenote..
Comments to these so far nascent thoughts welcome!
