Thanks Moderator.
And moondog, my flight is originally a return flight from NY to Melb, I've extended my stay in Beijing. The price I paid was around $2400 return, it was peak season and in economy.
I bought the tickets through an agent. I really don't want to buy up as I have paid more than I was willing to.
They told me to call every day and check, but that chances of getting a ticket is slim.
What's your opinion?
