26 Sep 2025 | New York
KBRA assigns a long-term rating of A to the City of Chicago, Illinois (the City) Chicago Midway International Airport (Midway or the Airport) Senior Lien Revenue and Revenue Refunding Bonds Series 2025A (AMT) and Series 2025B (Non-AMT). KBRA concurrently affirms the long-term A rating on the City's outstanding parity Senior Lien Revenue Bonds issued for Midway. The Outlook is Stable.

The Series 2025 Bonds and outstanding parity Senior Lien Airport Revenue Bonds are secured by a pledge of revenues, payable after operation and maintenance expenses.
Key Credit Considerations
The rating actions reflect the following key credit considerations:
Credit Positives
- Strong, diverse, expansive air trade area supports origination and destination (O&D) passenger demand.
- Position as the fourth busiest airport in Southwest Airlines’ (Southwest) route system as measured by scheduled seat capacity.
- Residual airline use and lease agreement provides the basis for consistently sound financial operations.
Credit Challenges
- High level of carrier concentration, as Southwest accounts for nearly 90% of enplaned passenger activity.
- Historically narrow, but improving, debt service coverage as the Airport transitions to an increased rate covenant under revised 2023 Bond Indenture.
- Non-airline revenue performance ranks among the lowest of U.S. commercial airports.
Rating Sensitivities
For Upgrade
- Diversification of the carrier mix with concurrent enplanement growth.
- Successful transformation of terminal concessions, resulting in enhanced non-airline revenue support.
For Downgrade
- Significant reduction in Southwest's operations at Midway.
