I booked tickets for my In laws . My mother in law has no last name in the passport .
At the time while giving her the Visa , USCIS has issued the Visa with First name as FNU and Last Name as Laxmi Jaiswal.
I booked my flight tickets as per name in the Visa.
I did that because most of the American Airlines suggest to put the name as Last Name in case of Single Name.Below is the link of reference from American Airlines

They have clearly answered the question in case of Single name and suggested that -
"If the passenger's legal name is a single/one name; enter that as their last name. Use FNU as their first name in the Name Field of the PNR name."

According to the Etihad Customer Care and Feedback team this is wrong and I have to book the ticket as per the name in passport.
They say that I can not change the name in tickets as ticket is non refundable and I did not approach within 24 hours.

My question is that there if there is no spelling mistakes in name and only the First name and Last name are interchanged due to the Name mismatch between Visa and Passport. Since they have not addressed the concern in their website , I have gone with the advice of other airlines and booked ticket as per name in Visa.

Now they say this is not correct and passenger can not board flight. This is totally unacceptable.Please suggest me what I can do ?
