MUMBAI: Aamir Khan has been travelling a lot. A month earlier he left for a mysterious trip to Australia (apparently to learn dancing), and now he was spotted at the domestic airport leaving for another city.

Unlike most Bollywood stars at airports, Aamir Khan was seeing leaving in the early hours of the day, but he seemed to be in a jolly good mood even so early in the morning.

Aamir Khan was seen in a black and white mixed t-shirt on blue jeans and smiled for the shutterbugs as well as shaking hands with fans.

So where was Aamir Khan off to? Some training in another city this time, or is it just an informal trip?

‘Dhoom 3’ will release on 20 December, 2013.
