Like others in this thread I have reached a dead end at the end of the booking procedure using the online tool. It accepts my complete 16-leg itinerary beginning and ending in CPT, and allows me to select all the flights and dates I want (except, as noted above, BA, AA & JL code shares are never offered).

I enter my name, BA FF# and phone number (in US) and proceed to book it, but I receive an error message. I've tried changing my FF# to AA, and tried putting in the BA JNB phone number so that it appears to be a South African one, but to no avail.

I want to phone the BA JNB number to get it issued, but without a BA locator number it would appear to be a waste of time.

Dealing initially with BA US is a real pain, and BA UK won't usually help when they see that I am a BA Exec US member.

Any ideas welcome, PLEASE.
