Do we need visas for a 1 night trip to Chengdu from our Hong Kong stop-over?
Hi,
We are flying back to London from Brisbane via Hong Kong. On the same day we land in HK we fly to Chengdu, stay overnight, see the pandas and return to HK in the afternoon. We stay overnight in HK and leave for London the next afternoon. We are a family 4 UK citizens. We'd like a definitive written answer on whether we are covered by the 72 hour transit policy for Chengdu, that part of the stopover is less than 24 hours but we fly back to Hong Kong before returning home. The Chinese Embassy in London suggest we won't need visas but defer to Chengdu airport immigration who we could not communicate with. The airline for our return to HK have not responded to this question either. Ultimately we don't want to be refused entry to Chengdu to see the pandas on our daughter's birthday. We hope you can help.
Thanks!
