Apologies if this should be in another forum.

Booked a ticket from ATH-AUH-SYD through Aegean. Both flights are operated by Etihad, but price was better on Aegan site.

The PNR is Aegean, and there does not seem to be an EY PNR.

When I look at the booking, the only FF option is Miles&Bonus.

I have a Virgin Australia account and would prefer to use this.

Also have United, but this seems unlikely since it is an EY operated flight.

The final alternative is sign up for a Miles&Bonus account.

What are my options?

W class ticket.
