• The US DoT has waived an $11M fine against Southwest Airlines.
• The fine was imposed after a major operational disruption in 2022.
• Southwest has improved its on-time performance and invested $112.4M in NOC upgrades.
• The airline has paid $24M of the original $140M penalty.

This waiver may indicate the DoT's willingness to incentivize airlines to invest in operational resiliency, which could lead to improved passenger experiences and reduced disruptions. The decision suggests that the DoT values the efforts of airlines to improve their performance and invest in upgrades, which may set a precedent for future regulatory actions.
