It is suggested that you arrive at MDW 3 hours before an international flight and 2 hours before a domestic flight. If you have a morning flight you are strongly advised to check on the Chicago traffic before deciding how early to head out, especially in the winter. On-airport parking at Midway can be a hassle too. We recommend using Park 'N Fly parking at Midway. The airport was well known for having a high flight delay and cancellation rate. It is therefore also strongly advisable that you check your flight status before leaving.
