Flt. 952 is LAX - x ORD - DUS (953 back). Change of gauge at ORD. Both segs are 3 class usually. 952 out of ORD almost never left on time, when I used it. And I did it a lot. But ... if you're out of luck, this could be the one leaving on time.

Re to DEN and ORD cxns in November. Pleeeaase gentlemen: As if UA'S delay are weather related. The day of my worst travel experience ever (with almost NO plane leaving IAD without a min 1 hr. delay 9/10) happened to be a very sunny SUNDAY from the Great Lakes down to FL.
