I am flying from Jaipur->Mumbai, and then taking a 2:45am British Airways flight home. Am wondering how many hours ahead I should land in Mumbai? Ideally would take the Jet Airways flight that lands at 10:30pm, which would leave 4 hours for a layover, but am concerned since FlightStats says that flights into Mumbai are chronically late. My BA tix are F award tix so missing that flight is not an option. What do you guys think?
