The way I view it, I'd rather pay $350 for a year of AC access than an extra $350 for one domestic trip in F instead of Y. As someone who is a) young b) travels very frequently (5 TPACs, 1 TATL, 3 domestic since Jan 1) and c) who can afford it I have bought lifetime memberships in the AC, PC and WC lounges. It really depends on your choices...but I still think that lounge memberships are among the best values around.
