🧳 Preflight

Get your flights in. Then forget about them.

SecondLeg quietly assembles your trip — from your calendar, your inbox, or a quick search — and keeps watch from booking to boarding.

A living globe, not another list.

Your whole journey renders as glowing arcs across a 3D earth. Progress updates live — great-circle position when available, smart time-based fallback when it isn't. Search any route or flight number and it's on your globe in seconds.

🛫 At the airport

See delays before the airline admits them.

The two biggest causes of delays are late planes and ATC mandates. SecondLeg watches both — so you can rebook from the lounge instead of the counter.

Late planes. Spotted early.

We track your inbound aircraft and its turnaround window. If your plane is running late — even before the airline posts a new departure time — your delay forecast moves first.

Air Traffic Control mandates are the #2 cause of delays. SecondLeg reads the advisories — ground stops, weather, airport issues — and tells you what actually affects your flight, in plain language.

First to know. First to go.

Gate changes and delays arrive instantly and unfiltered — as a notification, a Lock Screen widget, or a Live Activity in the Dynamic Island. Every tracked flight also keeps an offline snapshot, so terrible airport Wi-Fi never blinds you.
