I have never been involved in an airport move, but I just experienced the move from Gimpo to Incheon. Demand dropped by as much as 50-70% on some long haul routes. Is this normal? For example, Chicago and Atlanta used to support 2 747 flights per day, but now Chicago is at about 1 747 worth of demand, and Atlanta even less than one. Will the demand slowly build back up, or am I in huge trouble?
It would seem that when Incheon opened, longhaul service to/from South Korea expanded rapidly.... not shrunk drastically.
