I booked sameday R/T travel on Trip.com for Shanghai-Yiwu-Shanghai for the first time since paper tickets were
eliminated. I was surprised at how well the entire procedure worked. Passport scans at security, boarding, and exit
went smoothly enough - I just learned that at boarding and exit I have to line up at the manual line rather than the
automated toll booths. I definitely liked the fact that I no longer have to line up an hour in advance at the ticket windows.
