Everything was good in the beijing PEK airport until a buggy service come to us during our transit time and offer to sent us to E51 on 22 Dec. And suddenly charge us 20 dollars for a 3 mins ride. Reason we board becoz got the airline logo on the veh. Not sure how many people got cheated coz he got a few dollars with him. Won't ever transit and come to this airport again! Security all very good but was cheated by the buggy service. Bad image! Beware!
