I'm a DL refugee - moved to AA last year and havn't looked back once! especially as I'm now EXP so there are no 500 miles upgrade requirements (i.e. upgrades are now free & I've been upgraded on every flight so far this year) in addition EXP's receive 8 VIPOWs good for an upgrade on ANY AA flight, including international (same as the old SWUs DL used to have) I even used two recently to upgrade on a supposedly very difficult flight LAX-LHR. Bottom line for this ex-Dl Plat member is a ^ for AA
