Monty Gordo,
Air India Yes looks like an incredible success over 80% load factor.
Air India did say that if it went well then they would increase it to daily and perhaps look at another destination from BHX.
Suppose it depends on the yield but seen nothing to suggest that is poor, from those handling it.
Its an ideal route and seating config and plane type for BHX.
Whether another route would work as well, might be being too optimistic but you never know.
