Like I said, mark my words. Heathrow capacity is approaching its maximum limit (I think it's 98% capacity at the moment), Airbus is looking to cut costs of producing the A380 in hope of recouping more of its investment, and Emirates is pushing for a more fuel efficient NEO A380. The A380 will pick up with later more fuel-efficient models much like the 747 did.

With BA looking to decrease capacity on certain routes and increase capacity on others, it is more cost effective to send a re-engined A380 instead of 2 777's, or an A380 instead higher frequency. Within a decade a re-engined A380 will be flying in BA colours. Let's come back to this post in 2024. Expect conversion of options when the re-engined option is announced. Aviation in the US and Europe has taken different routes. Europe focuses on fewer but flights on larger aircraft where the US tends to gravitate towards more flights on smaller aircraft.

I bet internal and external accounts/financial advisors are already working for/with BA to examine how best to incorporate the new A380 using provisional figures for the yet-to-be-officially-announced, but well-planned NEO model.
