Sitting in the First Class lounge in Mumbai T2.... Took exactly 75 minutes from leaving my Jet Airways domestic flight in T1B to arriving in the Lounge in T2. Longest wait was at the baggage carousel in T1B - 15mins. 10 min wait in line for the transfer coach. 20 min transfer between terminals. Took less than 30 mins to check-in and proceed through security, immigration and customs. Yes, there were several passport and boarding pass checks which were bureaucratic and largely ineffective... But it's India and having expected a nightmare, I was actually pleasantly surprised by the 'relative' efficiency.
