Air India — Abandoned passengers in Kolkata enroute bangalore with no arrangement to endorse them on another airline

Address:

560047

Myself and my wife were carrying ok tikets
Feb 13, 2017 from Kolkata to Blr. We were abruptly told at the chk in counter that the plane AI 774 was cancelled and they canceled our tsk and told us they will reimburse the 22000 freq flyer mileage.
No they refused to endorse the tickets.
We had to purchase tkts on jet airways and leave for Blr that day; cost us Rs 16000 plus
Another Rs 3000 for 14 kg excess baggage
That jet does not allow. Air India runs a shamefully inept airline. Deserve redress.
