Key Credit Considerations

The rating actions reflect the following key credit considerations:

Credit Positives

  • Strong, diverse, expansive air trade area supports O&D activity.
  • Ranks as the third busiest airport in its dominant carrier’s (Southwest) route system as measured by enplanements and scheduled seat capacity.
  • Residual agreements obligate airlines, mainly Southwest, to absorb necessary rate and rental charge increases.

Credit Challenges

  • High level of carrier concentration, as Southwest accounts for nearly 90% of enplaned passenger activity.
  • Narrow debt service coverage, reflecting an adequate, although strengthened, rate covenant and residual airport use agreement.
  • 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 Airlines operations at Midway.
