[Single Name on Passport]

I am traveling to Toronto from Chennai via Etihad with a layover and plane change in Abu Dhabi. My first leg of journey to Abu Dhabi is through Akasa airlines.My passport has only a single name, No Surname.

e.g. ABC as Given Name and Surname is Blank.

My travel partner has booked a ticket via Etihad and put my first name as ABC and Last name as LNU . I scroll through internet and found that according to Etihad policy the name on ticket should be FNU ABC.

Should I be concerned about my travel? Can anybody share their recent experience? My travel is within a month

Talked to etihad customer care they will not be able ti edit ticket before 24 hours of departure and it will cost fare difference.

Did google search where editing before 24 hours does not guarantee seats. Also some posts are there were people able to update at airport for free.
