I recently flew Thai Airways Business Class from Bangkok to Ho Chi Minh City and visited the Thai Airways business class lounge, Royal Silk Lounge. The lounge is available to Thai Airways Business Class passengers, Star Alliance Gold members and Thai Airways elite members.
Thai Airways operates three premium lounges at Suvarnabhumi Airport (BKK):
- Royal First Lounge (Royal First & Star Alliance First Class)
- Royal Silk Lounge (Business Class & Star Alliance Gold Members — covered in this article)
- Royal Orchid Lounge (smaller lounge)

Checkin
The lounge is easy to find, located just behind Thai’s private security and immigration area. At the entrance staff scanned my boarding pass and issued a Wi‑Fi login slip. Once inside it quickly became clear how large the lounge is — it felt enormous, and finding a specific spot took a moment.
Seating & Interiors
Royal Silk Lounge is an extended rectangular space that stretches a long way from the entrance. There are two entrances and the seating areas are arranged in blocks that help break up the expanse and create smaller, more comfortable zones.
The lounge can accommodate roughly 300 guests. Seating is functional and consistent throughout rather than luxurious or highly modern; you shouldn’t expect designer armchairs or premium recliners. For business travelers there is a small business centre with individual cubicles equipped with PCs and printers.




Kids Play Room
One of the partitioned areas includes a small kids play room. It’s compact but practical, offering a suitable space for children to play while parents relax nearby.



Food
Food stations are distributed across the lounge rather than concentrated in a single dining room. Several food counters around the space serve a variety of hot and cold dishes, with the main buffet area located near the centre.
While a dedicated dining zone with tables might make for a more cohesive experience, the spread-out layout can be convenient depending on where you’re seated. There is also a staffed bar at one end of the lounge; its location is easy to miss if you don’t explore the full length of the space.






Bottomline
This is likely the largest airport lounge I’ve visited. Despite its size, the Royal Silk Lounge doesn’t particularly impress with luxury finishes; it feels functional rather than opulent. Updated seating, a few recliners and refreshed interior design would lift the experience — a renovation could make a noticeable difference.
- Cardexpert Rating: 3.9/5
I was surprised to see the lounge regularly reach high occupancy levels — even at business class capacity it easily gets over 80% full.
