A TDP MP on Thursday allegedly went on the rampage, pushing an airline staffer and throwing a printer on the floor, after he was denied boarding by IndiGo for being late -- prompting a flying ban by the budget carrier as well as state-run Air India. While IndiGo had finally accommodated J C Diwakar Reddy of Telugu Desam Party, to which Union Civil Aviation Minister Ashok Gajapathi Raju also belongs, on the same flight this morning, later it decided to ban him from taking its flights. State-run Air India soon followed suit by barring him from its own flights.
