Ditching the luxuries of a business class, superstar Aamir Khan took everyone by surprise as he was spotted travelling in the economy class of domestic budget airline IndiGo. In a viral video, the "Dangal" star is seen sitting by the window seat quietly, wearing a pale blue cap and has his signature spectacles on. He looks amused by the attention he was receiving. Aamir was last seen onscreen in the "Thugs Of Hindostan" along with megastar Amitabh Bachchan, Katrina Kaif and Fatima Sana Sheikh.
