I have 4 F sectors coming up in the second half of the year. One using Avios using a 2-4-1. Decent value. One a cash ticket (yikes!!) – but that was purchased at less than business class on anyone else I consider half decent. BA F was £1595 r/t for LHR-AUH-LHR on the precise dates I needed. A comfy way to travel – Just. About says it all really.
