I am half done with my JNB run but just found this thread; looks like I travelled in parallel with Titom ORY-LHR-JNB-MAD without knowing, but I am staying one more night in MAD than they are...
I have added my remaining flights so if anyone is also flying MAD-LHR-JNB-LHR on the 26th/27th and wants lounge access, PM me.
