Thank you everyone. This is what makes Flyertalk a great community.
It's hard for me to justify spending $400+ to hit Platinum on UA and even the mid $300s isn't helping either.
On that note, if anyone is looking: LAX - CLT - SBY - PHL - LAX is $332.10 a/i leaving Thursday ($.06/mile..not great). I can't do a ML this week otherwise I'd consider taking it.
