I am interested in booking on Oman Air so also interested in this.
Unlikely.
About a year ago, I got an agent from Etihad who had the time and patience to work with me. We were booking to BKK from Oman, but I was using EY miles. After a few dates where I was flexible, I asked him to try 8 months out, 10 months out. Not one seat. Then we tried KL. Not one seat. I asked about success and he said not usually, if ever. He said inventory is not viewable from OmanAir, so they have to check date by date. Shoddy, shoddy, shoddy. Yet another hollow 'perk' from EY.
