He might be looking closer at AA flights

. Although you never know. In addition to the above, there is also
B6 363 940pm-607a (yes, B6... but it is a cheap 150)
VX 356 1045-720 (similar issue as B6, but can try a new airline possibly, same 150ish)
Sticking only to AA there is the 11:55-9:50am option through ORD - but that may be cutting it close. (180)
