Yes, well, for AA it's the third tier, for US, the 4th tier.

Another thing to note is that AA EXP, UA1K and US CP are all obtained with 100K EQMs vs. DL's 75K; US's 75K level, called Platinum Preferred, gets another SMS-type number, not the CP "Liaison" desk...

All this discussion (as well as the PMU discussion, etc.) leads me to believe that Delta should really think about creating an official fourth tier to recognize those who fly 100K or 125K instead of just occasional targeted benefits....as has been discussed many times before, most people don't see the need to go beyond 75K these days since there isn't really any recognition beyond that other than the 125K benefit (and now the secret EP level though that doesn't really count since it's not published).
