BoardingMaybe shows the real on-time rate, average delay, cancellation rate and best time to fly for any route — from 26M+ real flights across official government and airport data. Free, no login. Know before you book.

Hey PH 👋 I built this because "is this flight actually usually late?" is weirdly hard to answer before you book. Airlines don't advertise it, and the real data is scattered across a dozen government and airport sources that all format things differently. So I pulled ~26M flights from 11 first-party sources and turned them into a simple per-route answer: on-time rate, average delay, cancellation rate, best time of day to fly, and an airline-by-airline breakdown. A fun thing I found in the data: weather is directly blamed for only ~6% of US delays. The real villain is the cascade; one plane running late in the morning ripples through the whole day. It's free, no login. Would love feedback on what other cuts of the data would actually be useful to you.

Really useful tool, especially not needing an account. One thing that would take it further for me: a price drop or fare comparison layer alongside the delay data, so I can weigh cost versus reliability in one view. Right now I still have to jump to a separate site for ticket prices.

@hamidesevg79879 Thanks for the feedback, Hamide. Will definitely look into this!
