I've already booked my ORD-WAW-ORD flight on LOT; it departs ORD at 9:25 pm. I can get to ORD via United at either 4:29 pm or at 8:09 pm. I'm resigned to the 4:29 arrival, but is the 8:09 pm arrival possible? Also, I will be flying to ORD out of the boonies, which means I will be fighting my way out from the boonies of Concourse B. Thanks in advance!
