Lets pose the question the other way?
Q. Considering the RUH route doesnt start till mid september (at the earliest)... what's the BD A332 doing on the three days a week when its not flying to BOM ?
Considering that BD dont yet have all the authorities they need to sell this route and have the intention to go daily to BOM (with the additional frequencies the Indian government are allowing), I dont see the Arabian route happening at all.
Perhaps someone with a ATI password can confirm the !!!!!!!!!!!!!! rumours....
