In July, my husband and I will have a 4 hour (+4 minute!) layover in Chicago O'Hare. We will be coming from Seattle and continuing to London Heathrow (AA/BA codeshare so our bags are checked through).
My question is (assuming the first flight is on time) whether we will have enough time to meet a friend for a quick taste of Chicago style pizza (she is happy to meet us at the airport and provide the pizza!)?
We are not US passport holders, so I'm concerned about how long it will take to clear customs, or won't we need to if we're coming in on a domestic flight? We have the appropriate Visa/ESTA as we will be visiting the US for 2 weeks and this is our return journey.
Thanks in advance!
