Thank you to those that replied. Gibbon, to be honest I went with BA because the timings were most suitable. I have no particular affinity or otherwise with BA, have flown to CPT numerous times (no children) with Air Namibia, KLM, Virgin and Emirates. BA simply offered a good connection (less than 2 hours) at Terminal 5 and an overnight flight to destination, plus it’s easier to check in baggage (1 each, 2 car seats and buggy) at LBA (v close to home) and forget about them. Rather than the long drive to LHR followed by long flight.
On my own outbound, wife to help inbound thankfully. Thanks again for advice, I’m not expecting sleep but it’d be nice if those around me can get some.
Cheers
