On October 5, I learned that passengers with gold status on AA can no longer use the elite security line in Terminal 3. It's strictly first class, executive platinum, and platinum.
What I gather is that one lane is for TSA Pre passengers (and there aren't a lot of them), and the rest of the elites use the other line. So, to decrease the line for the non TSA Pre lane, gold is being excluded.
Is this being done at other airports and other carriers? I was in Boston yesterday, and the elite line for the AA side of Terminal B still has all levels of AAdvantage elites.
