I've booked a rtn trip to NZ and am due to travel from London STN - AKL in F at the end of the month. I've been told by an adviser to ring back 5 days before I'm due to fly out. To be honest I don't see the situation improving between now and then, so I'm considering my options. (Also the UK Govt has advised against travelling to the UAE, unless it's for essential travel. If I ignored that, it would invalidate my travel insurance.) If I contact them sooner rather than nearer the time it's been suggested and I come up with airlines and flight times in an F cabin, having done the research, will I be allocated those flights? Or, will they choose their own?
