Common questions · IAH departures
How do I know if IAH is delayed right now?
Check the conditions panel at the top of this page. We read IAH's live departures feed and show whether the schedule is light or busy right now, how many flights have already left, and how many are running behind. It refreshes through the day, so look right before you leave — and recompute your Leave-By Time so a busy morning doesn't catch you out.
How can I see IAH departures today?
The board on this page lists today's IAH departures straight from the live schedule feed — the time, airline, destination, terminal, and current status, soonest first. It covers flights leaving IAH itself; tracking one specific flight number gate to gate is better handled by your airline's app.
When is the busiest time to fly out of IAH?
It depends on the day, so we chart IAH's departures hour by hour and mark the busiest stretch. Mornings and late afternoons usually pack in the most flights, which means longer security lines. Fly out in a quieter window — or check the live IAH security wait first — and you'll usually get through faster.
What should you do if your IAH flight is delayed?
A delay can move your whole morning, so don't just sit on the old plan. Recompute your Leave-By Time with the new departure time, then check today's IAH security wait before you go — if the airport is quiet you may have room to spare, and if it's busy you'll still walk out the door at the right moment.
Does weather cause delays at IAH?
Often, yes — weather is one of the most common reasons departures back up. When it's slowing IAH down, you'll see it in the conditions and the board statuses above, because we show how today's flights are actually moving rather than forecasting the sky. If things are stacking up, recompute your Leave-By Time and check the live wait before you leave.
