I am kind of panicking about my hour and a half layover in O'Hare airport from Seattle. I arrive at O'hare at 3:17pm and my connecting flight to Rome leaves at 4:55pm. I am on American Airlines and so is my connection, so hopefully they will leave out of the same terminal. O'Hare is huge so I am nervous about a long hike to the gate. And it is too late to change my ticket. I booked in January. and my flight leaves in 5 days. I didn't begin panic until yesterday lol. My partner keeps telling me to not worry, but I haven't listened. Am I over-reacting?
