Recently, I found on SD that China Southern had great deal on SFO-Del route, fare that has since expired. I was not interested in flying, but fare was very tempting. My limited knowledge from reading here has been that for transit up to 72-hours no Chinese visa is required. However, when I was looking at the discounted itinerary, there was a note that mentioned otherwise. The note still shows today but no cheap prices anymore. Here is the exact wording from their site:
Note：72-hour Visa-free Transit is not applicable for stop flights. Please make sure you have the valid visa.
I am just curious why would this be?
I am just trying to be better informed so that if another good deal comes along, I know at least what to expect. I am a USA citizen if that helps.
Thanks.
