That's not a bad shout ATNotts.
However my concern would be for those pax transferring onto flights from DEL.
More and more people are using this service as a transfer point not just to other Indian destinations,but also to other points in Asia and beyond.
If we only have Amritsar direct,then are AI going to guarantee a number of seats on the DEL service for those wishing to either stay in DEL or transfer to another flight from the BHX end.
If memory serves,not that many passengers used the flight to get to YYZ from BHX,but very often it was full going back to DEL,which included pax joining the service at BHX.
My point is,I am not sure there is sufficient demand for 2 daily flights to DEL from BHX,let alone YYZ.I know there will be demand from India to Canada,it is a case of what seats are going to be made available to and from BHX in both directions,if that makes sense.
If AI go to double daily at BHX, it could be:
(1) DEL-BHX-YYZ-BHX-DEL;
and (2) DEL-ATQ-BHX-ATQ-DEL.
If not, it could be 4 days/week of one option and 3 days/week for the other.
That would eliminate backtracking and changing planes for pax between BHX and ATQ.
Again, pure kite flying.
