Enough for at least 3 x TATL UuAs to CW next year, by when this year's earn and burn and miscellaneous Amex spending will increase that by at least one more. Anyway, we're already booked through the rest of this year, so it's just earning for the next 7 months.
In fact, overall we earn more than we spend ... note to self, take more long-haul holidays
Is it time to actually spend a lot of ££££, book CW and UuA to First? But why? There's not a lot wrong with CW, and we'd rather spend the money on a longer trip (accommodation, F&B) and car rental (I like big US SUVs

).
