Flagstops
Weren't some of the BOAC European stops designated Flagstops (No Pax/Cargo Upload/Offload and were not Tech Stops as no fuel uplift/crew change required)?
Although I never worked for either BEA, or BOAC the poor relationship between the two carriers both before end after their merger had a direct impact on me (BUA/BCAL) five times - Three worked in my favour and twice it didn't. I found it all a bit sad. But when BA took over BCAL, I was told some apparently strange decisions were to ensure that another BEA/BOAC long term situation didn't happen again.
