Hi all! My friend and I are buying Zed Fare tickets on BA to fly from LHR to Cape Town in April. I've never purchased a Zed Fare ticket--can anyone give any advice?

Do we need to check in 4 hours early, so that we're at the top of the list? Of course we'd love first or business, but I don't know if British Airways upgrades non-employees and their registered companions. Any advice on Zed fares would be appreciated.

Thanks all!

Jacy...as ever...on the fly
