It has been a while since I last used my Priority Pass card and hence the best time to use it is when I fly Economy. Priority Pass has quite an extensive lounge list one can go in Suvarnabhumi Airport (although most of it is Miracle First and Business Class Lounge). As I was short on time, I just chose the lounge nearest to my departure point in Concourse E which is the Oman Air Business Class Lounge.
The lounge is fairly small, and is divided into a lounge section and a dining section. Food option in the morning was fairly limited but fair. Food quality was passable but they do have quite a fair bit of alcohol choices.
There are computers available in the lounge and also a shower room. As my flight was quite early, the lounge was not very crowded.
Given a choice, I would probably suggest one to try one of the Miracle Lounges within the airport. However, do note that the airport is quite big and hence choosing one that is not too far away from the gate is essential.
Some fake bubbly 😛
