I need to travel back from Bangalore to Zurich. On the outbound I am using LH on ZRH-FRA-BLR. On the way back, Lufthansa will not bring me to ZRH until 11.30am as their flight leaves BLR way after midnight.

Do you guys have any advice what would be the best option to arrive in Zurich a bit earlier?

The LX flight from BOM arrives at 6.15. I could take a plane from BLR to BOM something like 8-10pm and change to the LX flight which leaves at 1.15am. I have however not been to India before and I don't know if it is a drama changing domestic-international in BOM? Would 3hr be safe?

Although I would prefer the longhaul directly out of India and change in Europe to a ZRH bound plane, I wouldn't mind changing somewhere in India if it is time wise doable and it is somehow possible to have it on a LX/LH ticket. I guess this is the only way to be in ZRH early (sometimes around 9am would be nice).

I could leave Bangalore city around 4 or 5 but if required, I might shift it. It is on a Tuesday evening in Nov, arriving Wednesday morning in Switzerland.
Do you have any better options for me?

Thanks.
