Delivery to airport from Beijing, no more updates? RC168902743CN

I placed my order on November 17th, it said that the seller guarantees delivery withing 39 days so I was hoping it would arrive before New Year, because it is meant to be a present. However, I noticed that there are no location updates for the past 8 days (since December 16th) and I need to know if it will arrive on time, or I should start looking for a new gift... Is there anyone who can tell me how long it takes for the package to arrive after it arrives at the airport?
