I had booked my flight ticket from Bangalore to Patna(ref no - 2909103492) with my name as "Abhinav Choudhary", but I have my as "Abhinav". Since It was mandatory on yatra.com to put my name and surname and so I used my father's surname "Choudhary" and I use it all the places wherever it is required, but all my documents have name as "Abhinav". When I enquired about it that will I face any problem regarding my name while onborading the flight, so they told that I have to cancel my ticket and book a new ticket with name as "Abhinav Abhinav", which i eventually did and lost INR1700 in transaction.

Now my question is "Is it wrong to use my father's surname for me whereever it is required?" and "if it wrong to use my father's surname then Why the yatra.com site has two mandatory fields for name, when In India many people are there with single name only? "

Dear Mr. Choudhary,
Thank you for contacting us at Yatra.com.
We regret the inconvenience this may have caused. Please be informed that in order to make a booking, both first name and surname are mandatory in the airline system and thus on our website as well. A valid photo ID matching the name on the booking has to be presented at the check in counters. This is a requirement by all airlines for security reasons and policies determined by them. Once again, please do accept our apologies for the inconvenience faced by you.
Should you require any further assistance, please call us on 987-1800-800 or alternatively write to support@yatra.com
Best Regards,
Yatra Care
