Source: US DOT T-100 segment reports, 2025, scheduled service. Mainline operations only — regional partners report separately. CO₂ is an estimate: miles flown × a representative fuel-burn factor per aircraft family × 3.16 kg CO₂ per kg of jet fuel (±15%; factors cover 100% of reported miles — types without a published factor are excluded — see the jet tracker methodology).
