Wednesday, August 12, 2026

BTS 26-63

The U.S. Department of Transportation (DOT) today released its Airline Service Quality Performance data compiled for the month of June 2026 for on-time performance, mishandled baggage, mishandled wheelchairs, and scooters.

The line chart illustrates the number of scheduled flights operated by Marketing Network Carriers and their branded codeshare partners, after cancellations, over the two years preceding the latest data release. In June 2024, approximately 643,000 flights were operated, increasing modestly to about 662,000 in June 2025, reflecting steady year-over-year growth.
