WHY ONGATE

Built to get you there — calmly.

To the minute
leave-by precision

Not a vague "two hours early." One exact time to walk out the door — and make it.

⏱️

Reverse-timed

We start at boarding and subtract every step, so the number is when to actually leave.

🚦

Live traffic & security

Real drive times plus each airport's typical security and immigration waits — not a flat guess.

🎯

Safe · Normal · Risky

Three leave times, three comfort levels — pick exactly how much buffer you want today.

QUESTIONS

Good to know.

How does OnGate know when I should leave?
It works backwards from your departure: live drive time to the airport, then typical check-in, security, immigration and the walk to your gate.
How accurate is it?
It's a strong guideline built from real airport timings and traffic. Conditions change, so we show Safe / Normal / Risky options — always keep a little buffer.
Do I need a flight number?
No. A flight number auto-fills everything, but you can also just choose your airport and departure time.
Which airports does OnGate cover?
We're live for Bangkok (BKK & DMK) and expanding quickly. Don't see yours? Request it in the app and we'll prioritise the busiest ones.
Does it handle international flights?
Yes. For international departures we automatically add immigration time and the longer check-in window, so your leave-by time already accounts for them.
Will it remind me when it's time to leave?
Set a reminder and OnGate notifies you the moment it's time to head out — and nudges you earlier if traffic builds.
Is my data private?
We only use your trip details to calculate times. Location is used to estimate drive time and is never sold. See our Privacy Policy for the full picture.

Never sprint through an airport again.

Your exact leave-by time — for every single flight.
