Oh, I don't think HAL will be in any hurry to pursue this opportunity. It
currently has much more pressing concerns. It's much more likely to
prioritise the re-development of the central terminals, given the current

close a wing of it permanently, and accelerate the expansion of T2.

This is so true. The costs and impact of trying to change a tyre whilst moving
vs. being able to take a more optimun approach must be significant. The question
will be how to finance this when revenues are down from landing fees and retail
sales.
