Every trip.
Every day abroad.
One quiet planner.
Sojourn is the calmer way to plan flights, log past trips, and track how many days you've spent outside the UK — built for people whose calendar matters legally.
Three things, done properly.
Plan a trip
Round-trip or multi-city up to three legs. Pick origins, destinations and morning-or-evening — we surface British Airways first, then everything else, side-by-side.
Log past trips
Whether booked elsewhere or taken before Sojourn, log every prior trip in seconds. Days outside the UK roll into your annual counter automatically.
Stay under 90
Set your reference date once. We compute the rolling 12-month total and warn before you cross it — green, amber, or stop.
Let your assistant do the planning.
Invite an assistant by email. They get their own login and book everything on your behalf — same trips, same counter, full audit trail. You stay in control; they save the time.
- ✓Read-only audit log of every change
- ✓Switch between multiple principals from one account
- ✓Unlink any time — no data is shared, only delegated
Why most spreadsheets get this wrong.
The SRT counts days in a moving 12-month window — not Jan-to-Dec. Sojourn rolls automatically every day.
Departure and arrival dates count. Our day-counter does the inclusive math so you don't have to.
Booked, manually-logged, assistant-added — every trip touches the same counter. No double-counting, no gaps.
