They cancelled the flight !!
Cons: The flight was at first delayed by 3 hours because of a technical issue. At first they delayed us by an hour an a half, and added another hour and a half delay to it after the 1st slot. The delays were announced at the last moment. Then Air India sends us for dinner, and while most people are at the restaurant, they announce at the gate that the flight has been cancelled. The few of us who were waiting at the gate were told to head to the transfer desk where alternate arrangements would be made. The Air India staff gave us no information on what these alternatives were or what options we had.
The transfer desk is operated by SQ. We passengers had to break the news of the cancellation to the staff at the desk . They had not received any intimation or direction from Air India yet and were unable to help us. SQ called Air India out of their own initiative to get the ball moving on how to assist us.
Still we had to queue up and wait for 20 minutes before Air India called SQ and gave some authorisation. There would be only 60 seats offered on the SQ flight the next morning on a 1st come 1st serve basis! What about the rest ? What if I wanted a refund ? No answers. Take it or leave it ! There was no AI staff to assist or even speak to.
Much later the people who were delayed at dinner and never made it onto the SQ flight were given the option of flying 25 hrs later by another AI flight.
While technical problems happen , what disappointed me was the lack of communication. No reasons, no proper alerts. Nothing at all from AI.
