2025 U.S. Airline On-Time Performance Was Worst in Over a Decade, PIRG Finds

U.S. flight punctuality hit its lowest point in 11 years in 2025, according to a new consumer research report.

American air travelers experienced more delays in 2025 than in any year since 2014, according to the 'Plane Truth 2026' report published by PIRG, the Public Interest Research Group. The report tracks on-time performance across U.S. carriers and flags 2025 as a notable low point in a decade-plus of data. The sources provide limited additional detail on the specific on-time rates or which airlines performed worst. A separate report notes that at least one airline has canceled eight routes to the United States, with many of those cuts taking effect by October. PIRG is a federation of state-level nonprofit consumer advocacy organizations that has tracked airline performance data for years. Its annual reports are commonly cited in policy discussions around passenger rights and airline accountability.

Why it matters

Deteriorating on-time performance affects millions of travelers annually, with cascading effects on connections, business schedules, and passenger costs. The trend may intensify regulatory and consumer pressure on airlines to improve operations.

What's next

Several international routes to the U.S. are scheduled to be fully phased out by October, which could further reshape flight availability for travelers.

Key facts

• 2025 had the worst U.S. airline on-time performance since 2014, an 11-year low
• The findings come from PIRG's 'Plane Truth 2026' annual report
• At least one airline has canceled eight flights/routes to the United States
• Many of the canceled international routes are being phased out by October 2025

Bias & framing notes

The two sources cover essentially unrelated stories — one about industry-wide on-time performance data, the other about a specific airline canceling routes — making it difficult to synthesize them into a single coherent event. Neither source provides granular data, airline names, or methodology details, limiting verification. The PIRG report headline from Source 1 appears to be accurate reporting of a published study, while Source 2 is vague about which airline is canceling routes.
