Hi - I doing a mileage run in December and flying LAX-LHR-BLR r/t on BA arriving at 5am in Bangalore from London and departing at 7am back to London (presumably on the same BA plane). So the question I have - is 2hrs enough? I am not sure whether I need to go through immigration and customs and then check in again or if there is some transit route that is faster (I will have no checked baggage). BA customer support service is saying that I need to check-in 2hrs prior to departure but I don't think they appreciate what I am trying to do.
Also, will I need Indian visa (EU citizen) just for the transit? - not a big deal - happy to get them - just worried about the transit time.


Thanks in advance for any help.
Clive
