In Muscat, unless you are flying Oman Air, you will most likely be directed to the Primeclass Lounge.Located on the second floor, past the duty free section, this lounge is welcome to elite members and premium class passengers of select airlines, as well as Priority Pass holders. You can get a complimentary Priority Pass membership with the American Express Platinum Card.
Food and Drinks
Food and beverages were solid and served buffet style. The rotation was quite frequent and there was a huge selection. For the bar, there were a lot of choices for liquor but they did not have any special or themed cocktails that you find in some other lounges.
I was about to board a short haul business class flight to Abu Dhabi on Etihad Airways and was able to get a nice meal in before I left the lounge.
In general, lounges in the Middle East are quite opulent. They have lots of amenities and the quality of food is quite tasty. This particular lounge had a bank of PS4s as well as a pool table to entertain the kids (or your inner-child).
For those who are flying on business or first class tickets you are eligible for a complimentary spa treatment for your back or feet.
Remember to get a spa invite when checking in at the front desk, though you may be able to sweet talk your way in with just a premium class boarding pass.
Muscat is not as common of a Middle Eastern hub as Doha, Abu Dhabi or Dubai but the amenities they have in this lounge were quite impressive. It would be great to fly through this airport (and lounge) sometime soon and hopefully compare them to the Oman Air operated lounge.
