A Watchface for Airline Crews
Ever been halfway through a PA and forgotten your flight number?
Ever stopped for a coffee, then found yourself wondering, "Was it B27 or C27?"
After a 14-hour day, the last thing you want to do is try to remember your flight number when the hotel asks for it.
That's why I built Next Leg. It keeps your flight number, route, gate, departure time, and current flight status on your wrist, so the information airline crews need is always just a glance away.
Features
• Displays your current or next flight at a glance.
• Flight number, route, gate, departure time, and current flight status.
• Automatically follows your schedule throughout your trip.
• Displays the local calendar date and current Zulu (UTC) hour.
• Automatically enters Flight Hold and Hotel Mode after your final flight.
Display Explained
Local Calendar Date
Displays the current calendar date in your local time zone.
Zulu Hour
Displays the current UTC (Zulu) hour for quick operational reference.
Report Time Lead
Choose how long before departure your report time is calculated. For example, a setting of 0100 displays a report time one hour before the scheduled departure.
Flight Hold
After your final flight arrives, Next Leg continues displaying your flight number and calculated report time for two hours. This gives you easy access to your flight information when checking into hotels, boarding hotel vans, or whenever you're asked for your flight number after a long duty day.
After the two-hour Flight Hold ends, Next Leg automatically enters Hotel Mode, displaying only your next report time to keep the display clean and uncluttered.
Six hours before your next scheduled report time, Next Leg automatically exits Hotel Mode and returns to the normal flight display, showing your next flight number, route, departure time, gate, and current flight status so you're ready for your next duty period.
Getting Started
1. Create a FlightAware AeroAPI account at https://www.flightaware.com/aeroapi/.
2. Generate a personal AeroAPI key.
3. Copy your AeroAPI key into the Next Leg settings.
4. Paste your flight schedule into the app using the format shown in the settings.
5. Enter your airline's IATA or ICAO code (for example, AA or AAL).
6. Save your settings and you're ready to go.
Your schedule can be entered manually or quickly converted from a screenshot, PDF, or crew roster using an AI assistant.
Free Mode
Free Mode is enabled by default.
FlightAware currently provides up to a $5 USD monthly usage credit for Personal AeroAPI accounts. Free Mode is designed to help keep your monthly AeroAPI usage below that credit by automatically stopping live flight lookups before the limit is reached.
For most users, Free Mode should provide more than enough API usage for normal day-to-day flying without incurring any additional charges.
If you require additional AeroAPI usage, simply disable Free Mode and choose your own monthly usage limit.
Important
Next Leg is provided for convenience and situational awareness only.
It is a secondary source of flight information. Always verify flight information using your airline's official systems. Flight numbers, gates, departure times, delays, and other information displayed by Next Leg may occasionally differ from official operational information.
