In 2023, Southwest Airlines' reputation for reliability was under intense scrutiny following their catastrophic operational meltdown in late December 2022. While the airline spent much of 2023 investing over $1 billion in IT upgrades and crew scheduling software (specifically the GE Digital "SkySolver" system) to prevent a repeat of the "point-to-point" system collapse, the year was characterized by a period of recovery and regaining passenger trust. Statistically, Southwest's on-time performance in 2023 fluctuated, often trailing behind competitors like Delta and United in major rankings. However, their "reliability" in terms of customer-friendly policies—such as two free checked bags and no change fees—remained a strong differentiator. By the end of 2023, the airline had successfully implemented new "winter-ready" operational protocols and increased de-icing equipment at hubs like Denver and Chicago, showing a significant improvement in their ability to handle weather-related disruptions compared to the previous year.
