In an earlier life (circa 1970-1980) I lived and worked in Saudi Arabia. Coming from Cornwall, I spent my R&R breaks in the Duchy so I was a regular Brymon passenger from Newquay to Heathrow to connect with either the Quantas or Gulf Air flights to Bahrain or, occasionally, the BA flight to Dhahran.
A lot of Cornish guys worked in KSA and there were sometimes 6-7 transferring from T1 to T3.
On a couple of occasions, if the Brymon was running late or delayed in the hold at LHR, the cabin crew would identify the transfer pax who were allowed off first and who were then bussed, with their bags, directly to the Gate at T3.
I have been off one aircraft and boarding the next in as little as 15 minutes.
I guess the current security hysteria would put an end to all that even if NQY-LHR was still possible
