Guides & Research
Guides for choosing an airport-arrival deadline and research explaining how MakeItBy evaluates flight reliability. These resources support planning; they cannot predict an individual flight's outcome.
Determine the latest acceptable flight arrival by allowing for baggage, ground transportation and cruise terminal requirements. Includes a hypothetical example and a link to compare the flights you're considering.
Observed arrival success at seven deadline buffers from 0 to 180 minutes, using January 2022 through June 2026 BTS records. Includes counts, cancellations, diversions and bounds for unknown outcomes.
Historical analysis of 5.19 million July and October flight operations from 2022–2025. Compares arrival within one hour of schedule, accounting for route, operating airline and scheduled-arrival period.
Review historical calibration, reliability comparisons and the limits of predictions based on past flight performance. These are validation results, not a current-day forecast.
Already have two to eight U.S. domestic nonstop flights on the same route? Set your latest acceptable arrival and compare their estimated deadline reliability.
