Asiana Club - Heathrow problem

last night I was due to fly OZ521 to ICN. Two major road accidents around LHR prevented me from doing so, and I arrived with a colleague just too late to board. A few Koreans were in the same boat.
We had discounted biz tickets- it'll be interesting to see how we can get out of this. OZ Res were shut of course by 9pm on a Sunday. Ideally I'd like to commute my ticket to FRA-ICN today.
Anyone know if that's possible- presumably with a cost uplift.
o/wise it's going to be mass phone calls starting at 9 am when most reservations offices open.

One of many reasons why I take the LHD Express!

You've just missed the Sydney Reservations office (6pm Monday local) but I reckon you might have some luck finding an internet cafe and calling an international reservations centre with your credit card handy.
