In a perfectly fair and sensible world, this award would require 30,000 Avios, since the service is more like biz class than true F class.
But we know that these types of things don't always make sense. In fact, sometimes these things work in our favor, i.e., CC point offers, previous BA Biz class awards from USA to South America (inc. Easter Island) for 80K miles RT, etc.
One of the primary ways in which FT is helpful to me is by steering me towards the good values and away from the poor values.
