no real question here...but as DM's we are entitled to guaranteed seats on flights (subject to their rules which is typically 24 or 48 hrs before the flight with min booking class of V in economy). This is great for us last minute travelers, but I just can't understand why it can't be done online.

the system should easily be able to apply your guarantee seat to full flights when you log-in online and try to purchase a ticket.

it's not a huge deal to call up e-services, or ticketing when in HKG, but when travelling it's quite a pain.
