MCT Heathrow
Hi everyone - I suspect I should know this, but its a donkeys age since I transferred through Heathrow to a BA domestic. I am arriving on BA56 from JHB and want to travel up to MAN to get to Chester. Given they are both T5 departures - whats the minimum time I should leave? (have yet to book LHR-MAN, but have booked JNB-LHR as its part of a bigger itn).
Thanks in advance
