Greetings,
I've seen that 35 minutes is the minimum time for a dom. to int. connection at ORD but is this practical in reality especially if I am checking a bag?

I have the following AA award ticket on hold:

7/13 AA1239 dep SEA 15:54 arr ORD 21:21
7/13 AY10 dep ORD 22:00 arr HEL 14:50 (+1)

Somewhere in the booking process mentioned a terminal change but I can not find any info on AY10, i.e., dep. terminal.

I suppose there is a chance that space will open up on an earlier SEA > ORD flight and I would be able to change that flight but I don't think I should count on it.

Thanks.

Jon
