Well, migflanker...thanks for the "welcome" and thanks in advance for the flare ! There are a few posts here that give some hints but they are quite old and the industry has changed a lot since most of them, especially the Star Alliance vs. OneWorld relationships. My spouse F/A is on the legacy US side of the US-AA merger and does exclusively international and the switch from Star to OneW is not very well liked by the customers she flies. She REALLY wants to get to South Africa for her bestie's 50th so any assistance is really appreciated. They are going on DL from ATL-JNB so no hassling with KLM, but the PHL-AMS-CPT on KLM remains the best for us at this moment.
