Flight from Chicago O'Hare Airport to Pittsburgh

EmmaleeFlew with Southwest-Oct 2026

Don't choose an evening return flight because delays throughout the day will compound. The same issue happened the last time I flew to Chicago in 2024, the flight arrived at the destination after 2am.

RogerFlew with Japan Airlines-Jun 2025

Make sure when you go from one airline to another that your bag is marked properly so they can get it on the right damn airplane. I did that and it still didn’t make it.
