Rebooking due to tight connection in CHO
I have an award flight booked IAD-CHO-ORD-ARN. I just noticed that the connection time in CHO is only 24 minutes. I can't see a MCT for CHO anywhere, but clearly this is legal according to UA, since this is how the ticket was sold to us (not a schedule change). We are traveling with a lap infant and aren't familiar with the CHO airport, so I'm concerned we'll miss our CHO-ORD flight with even the slightest delay and then the ORD-ARN flight as well (since CHO-ORD is the last flight of the day). I probably shouldn't have booked this given the high likelihood of getting stranded in Charlottesville. Am I likely to have any success requesting different flights with a longer connection time?
