I need to leave China for a visa run within the next 3 weeks and am thinking about going somewhere nice (Europe) instead of the usual Hong Kong trip, or even trying the potentially horrible Mongolia tour.

So I'm wondering if there are 'stand by' flights available from Beijing (where you just go to the airport and ask the airline staff if they still have seats available shortly before take-off at a low price).

I figure it's not common here, because Chinese nationals would need a visa and tons of other planning for a trip to Europe, but is it possible, if you just go there as European? Has anyone tried this?

Thanks
