Yea! She is almost on the ground at O’Hare (ORD)! Audrey in on UA #907 from Munich (MUA). Then UA #108 to Las Vegas (LAS). She was probably in MUA the same time as Frauke
She is on her way back from a month at Ludwig Maximilian University of Munich doing research for her dissertation.
[Update I]: On the ground! Cha cha cha!
