How did you deal with www.aerohkg.com? Just over the web or via phone? Have you dealt with them a number of times in the past, or was this a first time?

I'm just curious how confident people are with using out-of-the-country travel agencies (I'm assuming you're physically in England right now? or maybe in Hong Kong since you just "picked up your ticket").

As for assigning those seats, I guess you'll have to try to score them the day of flight (I'd say try 24 hours before the flight and then if that doesn't work, try to get 'em assigned just over that 3 hour window).
