Did some googling but found nothing.
Even the Air India Chennai Lounge page annoyingly does not outline their hours. Reviews of the lounge say it is a bit run down with sparse food etc, and flakey or non-existent internet, but better than nothing and wonder if it is open in the early hours? i.e. do AI flights leave early am?
Thinking of a Business Class trip to Andaman Island for Xmas which leaves MAA at 5.05am and my flight arriving into MAA will be 11pm or so. So sitting in any lounge for 6 hours, even nice ones in Asia etc is never fun, but better than sitting in main hall!
Thanks for any first hand info.
