I was a regular on the DXB and AUH runs for many years.
The cheapest Y return on BA over 10 years ago was over £770
I can buy the same ticket today for £450
Business class fares are also a lot cheaper to DXB/AUH than a comparable transatlantic.
importantly, the A380 can generate better revenue elsewhere.
BA have been using the 777 since the mid 1990s and still use the same aircraft today...
So, as much as I would like to see it,(380) I don't think it will happen.
You could try flying QR to boost your tier points and get your self up to silver.
If all else fails, when relaxing in the flat bed, you could consider what it was like when BA had 767s on the run before the cradle seat! I remember it well!
