HKF:
Try this RL:
http://dps1.travelocity.com:80/farer...26043967743783
It allows you to get a complete published fare listing for all airlines between two points, for any day. It may not work, in which case, go to
www.travelocity.com and follow the links for a guest to
Fare Listing. You can probably experiment a little and find some
very high fares.
My quick search (the results are at
http://dps1.travelocity.com:80/fared...26043976146798 ) give an IATA fare, typically the highest, of USD$7924, return coach.
Good luck,
