Address:

400614

I have booked domestic flight tickets for 4 pax online through yatra.com from mumbai to kozhikode on 22/04-2018 in the flight 9w2421 paying rs.26, 466/- i have noticed slight variation of name from the aadhar card and in the ticket as follows.
Name in the ticket name in the aadhar card
1. Sasidharan katirattil k. P. Sasidhran (Sr. Citizen
2. Susheela sasidharan susheela (Sr. Cityzen)
3. Divya das divya. S
4. Master anushka das anushka (4 years old)

As soon as i have noticed the mistake, on 12th april i have talked to yatra.com & they said they will not be able to change the names. Airline is not permitting to do so.
I was forced to cancel the ticket and a whopping rs. 17, 906 they have deducted. & passed on refund on only rs. 8560/-
Although there is a concession available for senior citizen, they did not parted that benefit.
After cancelling and while re booking the ticket, its cost has gone up to 32, 918/- as against rs.26, 466/- of my first booking incurring another rs.6452/- extra.
Overall i have lost an amount of rs.24, 358/- simply a refusel of small corrrection of the name as indicated above.

I ahve to cancell my booking loosing heavly & rebook it at an higher rate.
Over all i have lost rs.
