Has anyone flown BA to/from the new Bangalore airport yet? I have a couple of questions

• First, and most important, is there a lounge?
• How long does it take to get there from Bangalore centre? (I'll be getting my hotel to drop me)
• How long did it take to go through check-in security?
• Is it as rough as Mumbai to pass-through?
• Anything else I need to know?

I fly next week, any help very much appreciated. A Swanhunter guide would be even better
