First name / Last Name Change
 

Dear,

I have booked a ticket to travel from Bangalore to Paris on 23-Feb-2016.
In the passenger details I have given part of first name in Last name column.
Eg:
In Ticket:
First name : Ram
Last name : Gopal

In Passport:
Given name : Ram Gopal
Sur name : Varma

I'd like to know will it cause a problem?
If so, how to change it without cancelling the ticket.

I have booked the ticket on Etihad website. No third party booking.
Please let me know the procedures.

Thanks in advance.
