Wake-up times for a 10:00 AM flight
Every row assumes a 30-minute trip to the airport and 45 minutes to get ready at home. Change those in the calculator below.

A 10:00 AM flight looks civilised — the alarm still decides it
A 6:45 AM alarm feels reasonable, which is precisely why it gets treated casually. You go to bed at your normal time, maybe later because the flight "is not that early", and then the one morning you cannot be late is the morning you hit snooze twice. The margin on a 10:00 AM flight is thinner than it looks: miss the wake-up by forty minutes and the check-in desk is closing as you arrive.
Go to bed as if the flight were two hours earlier. The buffer is what saves you.

How this is calculated
| Step | Time | Why |
|---|---|---|
| Your flight leaves | 10:00 AM | The fixed point everything else counts back from. |
| Arrive at the airport | 8:00 AM | Airlines want you there 2 h ahead for this flight type, so check-in and bag drop are still open. |
| Leave home | 7:30 AM | Your 30 min of travel time — traffic and parking at 4 AM are kinder, but the train may not be running yet. |
| Wake up | 6:45 AM | The 45 min you need to shower, dress, eat and find your passport without panicking. |
The alarm is the part that fails
Almost nobody misses a flight because they misjudged the traffic. They miss it because the alarm did its job and the person did not. In the first minutes after waking, the rational part of your brain is still offline — swiping an alarm away is a reflex you can perform while asleep, and afterwards you genuinely do not remember doing it. An alarm that only stops when you complete a real task — walk to the bathroom and scan a code, do the squats, solve the maths — forces you awake before your hand can cancel it.
