Complaint is regarding Vistara Airlines. I had booked tickets for 10/12/17 from Srinager to Lucknow which was scheduled to takeoff at 16.30 hr to Delhi and at 7.10 hr on11/12/17 onwards to lucknow. Our ticket I’D is ############. We had also return ticket in 17/12/17 from Lucknow to Srinagar. But to our surprise Vistara UK-977 did not takeoff when other flights were taking of and lending ontime. we were denied next day flight despite the reason Vistara is shuttering in routine and tickets are being booked online for tomarrow however on exorbitant rates. we were not adjusted in any other flight or next day flight despite verbal requests to officials of company.This is highly objectionable as we have missed our training programme which is must for our promotion besides have to bear loss in cancellation of return tickets. Hope you will proceed against defaulter and make arrangement for our travel or compensate loss.
