Every trip.
Every penny spent.
One quiet planner.
Sojourn is the calmer way to plan flights, log past trips, track travel expenses, and monitor how many days you've spent outside the UK — built for people whose calendar matters legally.
Four 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.
Track expenses
Log costs per trip in any currency — flights, hotels, transfers, meals. Totals roll up per trip and across the year, with one-click export whenever you need them.
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
Know what every trip really costs.
Log flight costs, hotels, transfers, and meals against each trip. See totals in your home currency and export everything at tax time — no spreadsheet required.
Log expenses in the local currency. Sojourn stores the original amount and conversion so your records stay accurate even when rates change.
Every expense sits inside its trip. Filter by destination, date range, or category to see exactly where your budget went.
Download a clean CSV of all expenses per trip or across the year. Hand it straight to your accountant or paste into your own tools.
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.
