Can I catch Beijing Airport bus 1 if fly arrives ar 0.15 am?

Hi, would you mind confirm the hotel's address again, so that I can help you to find the best method. Presently, I cannot find your hotel's exact position, since there are many branches of Super 8 in BJ.
Generally speaking, you can still take the airport shuttle bus after you arrive and only the shuttle bus line 2 (night line) is available. The shuttle bus + taxi will be the cheapest way for most cases.
