Chicago Midway Airport: 88 Delays, 16 Cancellations April 2026

Chicago Midway International Airport (MDW) recorded 88 delays and 16 cancellations on April 4, 2026, as Winter Storm Kadence disrupted routes connecting Chicago to New York, Dallas, Miami, Denver, Cancun, and Toronto.

Context and Background

Midway's disruptions run parallel to the far larger crisis at O'Hare (ORD), which logged 250 cancellations on the same day. Winter Storm Kadence — the same system generating dangerous ice and snow across the Northern Plains and Great Lakes — is the primary driver of schedule breakdowns at both Chicago airports.

Southwest Airlines, which dominates operations at Midway, bore the greatest operational burden at MDW. Southwest operates the majority of Midway's domestic capacity, meaning its delay rate directly controls overall airport performance. FlightAware data confirms bad weather as the primary causal factor across all MDW disruptions today.

Breaking Down the Routes Most Impacted

Disruptions at Midway cascaded to the following key destinations:

New York (LGA/JFK) — high frequency domestic corridors hit by cascading delays

What This Means for Travelers

Passengers transiting through Midway today should not expect conditions to stabilize until at least Saturday, when temperatures begin to moderate in some affected areas. Those on Cancun or Toronto routes via Volaris or any interline partner should confirm directly with Southwest or their operating carrier about rebooking options under weather waiver policies.

Travelers who can rebook to Sunday or Monday flights should strongly consider doing so, as Easter weekend volume plus storm recovery could extend MDW congestion through Saturday.
