I do fly the LCC airlines in SE Asia a fair bit. I've found that they offer an equal or beter product at a lower price. Since that's not the essence of this thread, I'll be glad to elaborate more in a future thread.

Many countries have annual Lounge Memberships... Air Canada Maple Leaf Lounges, United Airlines Red Carpet Club, etc. I'd love to see a TG offer Royal Orchid Annual Membership too.

I think the majority of LCC passengers are too price sensitive to make overcrowding from membership attendence a contributing problem.
