United.com says United ticketing is available at ORD from 4:15am to 10pm.
What I'm looking for is what time the separate ticket office (you know, the one over to the left of the elite check-in area?) is open this Sunday.
I'd rather deal with them then the regular check-in agents who tend to be pretty clueless.
I am going to be attempting to combine a Type A and Type B voucher, so wish me luck
