Elite when I was 23 alongside my first J TATL flight. Super Elite since 26 (I'm now 30).

Similar experience to Sean Peever: It all depends on what I'm wearing. Long TATL/TPAC flights typically mean shorts and a t-shirt (I always find the cabins too hot) so I've historically run into check-in and gate agents trying to usher me to the "correct" line.

Used to get quite a few comments from FAs after they check the PIL. Not so much the last year or so (I guess that's what happens when you turn 30 ).
