Helpful tips

⏰

Your alarm is a floor, not the plan

The planner calculates the latest safe wake-up time. Set a second alarm 10–15 minutes earlier as insurance. Delays compound, and rushed mornings make everything worse.

🔒

Security queues are unpredictable

The default security estimate is a peak-hour average. Early mornings and Sunday evenings are reliably slower. Holiday periods can be double. Adjust the slider to match what you know about your airport.

🚖

Add taxi wait time, not just travel time

Ride apps show an ETA, but that's for the best-case scenario. Factor in the time it takes to actually request and confirm a car, especially in bad weather or at peak hours.

🌍

International flights need more runway

Passport control, longer check-in queues, and distant terminals mean international departures typically need 30–45 minutes more than domestic. Switch to International mode to reflect this.

Quick reference

Alarm time departure − all buffers

Domestic flight arrive 90 min before departure

International flight arrive 2–3 hrs before departure

Train / event arrive 15–30 min early

Peak security add +15 min on top of avg

Gate walk (large airport) budget 15–25 min extra

How the planner works

It's not just when you leave.
It's everything that has to happen first.

Most people plan travel time from the front door to the departure gate. The Travel Ready Planner works the other way: it starts at your departure time and counts backwards through every step that needs to happen before you get there.

For flights, that means boarding buffer, security queue, travel to the airport, and time to arrive before the gate opens. For international departures, the queue and check-in windows are longer, so the planner adjusts the defaults accordingly. You can also pick your departing airport to calibrate the security estimate to that specific terminal.

For trains and events, the calculation is simpler. Consisting of travel time plus a buffer to be comfortably early. The principle is the same. The planner always gives you a single number: the time your alarm should go off.

The optional extras: get ready time, coffee, packing, taxi wait, snooze buffer, exist because those minutes are real and they add up. Most people know roughly how long their morning routine takes. The planner just makes it explicit.

Alarm time departure − all buffers − get ready

Domestic security + travel + arrive buffer

International longer security + check-in + 2–3 hr window

Extras coffee + packing + taxi + snooze

Common questions

The default figures are based on published peak-hour averages for international airports. They're a reasonable starting point, but no algorithm reliably predicts your specific queue on a specific morning.

Use the security slider to reflect what you actually know. If you're flying out of a small regional airport on a Tuesday morning, cut it in half. If it's Heathrow Terminal 5 on a Friday in July, add 20 minutes. The planner's job is to give you a structured estimate but your local knowledge should always override it.

Switching to International increases the default security estimate, arrive-early buffer, and boarding buffer to reflect the additional steps involved: passport control, longer check-in queues, potentially more distant terminals, and airlines that close gates earlier for long-haul flights.

As a rule of thumb, most airlines recommend arriving 3 hours before long-haul international departures and 2 hours for shorter international routes. Domestic is typically 90 minutes for larger airports, less for regional ones.

Knowing you need to wake up at 5:30 is useful. Knowing you need to be in the taxi by 6:45, at the airport by 7:15, and through security by 7:40 is more useful.

The schedule view breaks the morning into time-stamped milestones so you can see where the time goes and spot anything that feels off before the day arrives. You can copy the full schedule to paste into a note or share with a travel companion.

No. And it's worth being deliberate about this. The route calculation uses typical driving or transit time without live traffic data. Early morning airport runs are often faster than the estimate; rush-hour departures can be significantly slower.

Build in a buffer for traffic separately. If your route calculation shows 35 minutes, set the travel input to 50 if you're leaving during peak hours. The "snooze / wake-up buffer" in optional extras can also absorb small unexpected delays.

Yes. The Train and Event modes strip out the flight-specific steps (security, boarding buffer) and focus on travel time plus an arrive-early window. The same optional extras apply: get ready time, coffee, packing, taxi wait, and snooze buffer.

For trains especially, the arrive-early buffer matters more than people expect. Most intercity trains board 5–10 minutes before departure and close doors promptly. There's no holding the train the way a bus might wait.

Use the Copy button on the alarm card to copy just the wake-up time to your clipboard. The Copy schedule button copies the full time-stamped breakdown as plain text. Useful for pasting into a notes app, a message, or a shared itinerary.

The Add to Calendar button exports your morning schedule as an ICS file compatible with Google Calendar, Apple Calendar, and Outlook. Each step in your schedule is added as a separate event so you get individual reminders.
