How BoardFlight works
Most advice is a blunt rule: "get there two hours early." That wastes your time on easy days and fails you on hard ones. BoardFlight gives you one time for your specific flight — and tells you honestly how confident it is.
The model, step by step
1
We find your real flightYour flight number gives us the airport, terminal, scheduled departure, and whether it's domestic or international — the things that actually change how early you need to arrive.
2
We model each step of your journeyCurb to check-in, bag drop, security, and the walk to your gate — each estimated for that airport and that time of day, then combined.
3
We plan for a slightly bad day, not a disasterInstead of the average, we aim to have you covered on about 9 days out of 10 — so a normal slow day still won't make you miss your flight, without arriving absurdly early.
4
Built to learn from real reportsAfter a flight, travelers can tell us how security actually went. As those reports come in, they sharpen the estimate for the next traveler at that airport and hour — we're just getting that loop started.
What makes it trustworthy
Two things. First, the system is built to score every data source we use against real traveler reports as they come in — so over time we learn not just what each source says, but how much to trust it, airport by airport. Second, we're honest about uncertainty today: every part of the plan is marked as measured data or an estimate, and we never let an unconfirmed delay talk us into telling you to cut it close.
Frequently asked
Why does it still tell me to arrive by the original time when my flight is delayed?
A posted delay often gets rolled back, and boarding frequently proceeds close to schedule. Planning to a delay you can't rely on is how people miss flights. We show the delay for your awareness, but the safe arrive-by time stays anchored to the original departure. When the airline truly confirms a delay, we show it clearly.
What does "9 days out of 10" mean?
It means the plan is built so you'd be on time on roughly 9 out of 10 typical days — it leaves headroom for a normal slow day, without the waste of planning for a once-a-year meltdown. It's a deliberate, honest trade-off between safety and your time.
What is the "est." marker in the breakdown?
It flags a number that comes from a published estimate or a category default rather than data we've verified for that specific airport and time. As real reports come in, more of the plan becomes measured rather than estimated — and we show you which is which.
How do traveler reports help?
Each report of how security actually went gets compared against what we (and outside data sources) predicted. Over time this is designed to build a correction specific to each airport, weekday, and hour — the part of BoardFlight no one else can copy, because it'll be built from our own travelers' experiences. That loop is just getting started, and every early report counts more.
Does it cover the flight itself or after landing?
No. BoardFlight is airport-side only: from the curb to your departure gate. It doesn't track in-air time or anything after you land.
Is it free?
Yes. Checking your flight and reporting how it went are free.
