I'm trying to put together my flight history, and I am really struggling to find information about a trip I took back in 2011. The route was LHR-BKK via BOM, on 9W (30 NOV-16 DEC).

If it helps, I remember leaving LHR fairly early in the morning, arriving at BOM after sunset and connecting to a BKK flight that arrived early morning.

Inbound, the connection was also via BOM. If anyone happens to know the flight numbers, approx times and aircraft used on those routes, that would be really helpful.
