Recent data shows Spirit Airlines has an on-time performance (OTP) of about 81–82% in North America—ranking second among U.S./Canadian carriers in February 2025 with an 81.77% OTP . In April, its average OTP was around 80.8% (businesstravelnews.com). That means more than 8 out of 10 flights arrive within 15 minutes of schedule—solid for a low-cost airline, though still behind industry leaders like Southwest and Delta.
