Ah not as simple as that. The morning flight leaves about 10:40 so if I stay on booked flight then I can't make it. The next one is about 15.15 (off top of my head). A long wait! In that respect I'd rather they did move me to the earlier outbound as they I can make that 10:40 flight to Namibia. I just want to know soon so I can book that and relax. If I book the later flight to Namibia (based on my current flight they haven't yet cancelled) and then they move me to the earlier outbound from LHR that's a real PITA as I'll then be waiting 8hr at Jo'berg not the original 6, which would be bad enough.
