I am booked to travel on tonight's 32 which I desperately want to be on. However, as I am now expecting meetings to overrun here in TPE I will be rebooking my connecting flight to HKG.

The flight I'd like to move to is the CX531 and this will give me only 1:15 to make the BA32. I know it can be done (albeit outside my own comfort zone) but is it a legal connection.

Flights are contained in a single ticket.

Many thanks in advance for your guidance.
