Guys,
Thanks for all your help. In the end I decided that a trip in the North and South was too much stress. Now doing a tour of Kerala followed by a week at an Ayurvedic resort. Flights in F into BOM and out of BLR, with an overnight stop and 9W flights to Kerala.
£759 for taxes and charges with the 241, but this includes an offline booking fee the guy said he's waived

and a leg down from MAN.
Pre-allocated 4EF in an F empty cabin. Don't seem to be able to move myself, which I'm not sure I do.
TTFN
