New Delhi, Aug 28 (ANI): Soon after Air India announced an astonishing Rs 100 fare offer to celebrate Air India Day, the national carrier's website, where tickets were being sold exclusively, crashed. Some users who tried to go to the website got a 'Service unavailable' message. For others, the page would not load. Air India had announced that it will sell tickets for Rs 100 (taxes extra) for five days from Wednesday — which it will celebrate as Air India Day to commemorate the merger of erstwhile Indian Airlines and Air India in 2007.
