Flows start leaving next month - the first class has been assigned 3/3. Expect significant movement for the next 4-5 months. One thing to watch for, however, is that MSP will be shrunk via flows - CPZ can avoid paying relocation by simply assigning newhires and upgrades to LAX.

I'm not saying to avoid Compass, but temper your expectations on how soon you could hold "not-LAX". It might be a few months before you can hold MSP and DTW, but there will be a huge amount of attrition for the next couple years.
