I would be flying from Mumbai (BOM) to Port Blair (IXZ) in the month of February next year by Air India. This is the first time I would be traveling with connecting flights, earlier I have flown with direct flights. This is my itinerary.
Air India AI-570 06:15 BOM 08:10 MAA
Plane change at Chennai | Waiting: 2h 20m
Air India AI-551 10:30 MAA 12:40 IXZ
Is the waiting duration of 2 hours and 20 minutes sufficient? In case I won't be able to catch my connecting flight from MAA, due to delay in arriving flight, will Air India take care of arrangements?
