This is almost always the second question, right after "is this trip worth it" — and it gets answered badly in the same way: by picking a number of days that sounds right instead of one that's actually sized to the trip. Here's the sizing method I use with clients, built on the same logic an ER shift teaches you about recovery: it's a real, physical thing, not a scheduling inconvenience.
The Landing Buffer Rule
Every trip needs padding on both ends, and how much depends on two things: how far you traveled, and how much the trip itself demanded of you. I call the padding the Landing Buffer, and it's built from three rules.
- One buffer day for every three time zones you cross, before you're back to normal responsibilities. Your body doesn't know your flight landed — it knows it's still on the old clock.
- One additional buffer day if the trip involved more than two destination changes. Packing, unpacking, and transit are real work — they are not rest, however good the destinations were.
- Multi-city, high-logistics, or early-wake-up trips (safaris, expedition cruises, big elevation changes) need at least one full unscheduled day built into the trip, not just tacked onto the end of it. A rest day after a two-week trip doesn't undo two weeks of accumulated fatigue; a rest day in the middle of it does.
How Much Time, By Trip Type
| Trip type | Recommended minimum | Buffer |
|---|---|---|
| Weekend regional trip (0–1 time zones) | 2–3 days | None required — but don't schedule anything demanding for the return day |
| Domestic cross-country (2–3 time zones) | 4–6 days | 1 buffer day after |
| International, single destination (4–6 time zones) | 7–10 days | 1–2 buffer days after |
| International, multi-city (6+ time zones, 3+ stops) | 12+ days | 2 buffer days after, plus 1 rest day built in mid-trip |
Signs You Didn't Book Enough Time
- You're mentally drafting your out-of-office reply by day two of the trip, not the day before you leave.
- The itinerary ends the same day you fly home, with no buffer if anything runs long — a delayed flight becomes a missed Monday, not an inconvenience.
- You can list what you saw but not what you felt — a sign the trip ran on a schedule instead of a pace.
- You're already negotiating with yourself about which parts of "real life" you'll let back in on day one home, instead of just being back.
Why the Calendar Isn't the Real Question
Two trips with the same number of days on the calendar can need completely different amounts of actual time, because the calendar doesn't know how many time zones you crossed or how packed the itinerary is. This is really the Time Debt vital from the trip-worth-it check, applied specifically to length — the question was never "how many days," it was "how many days does this specific trip actually cost you." See Is This Trip Actually Worth It? for the fuller framework.
Frequently Asked
Is a long weekend ever really enough?
For a trip within zero to one time zones and a simple itinerary, yes — that's exactly what the regional-trip row above is built for. A long weekend fails the moment it's also trying to cover multiple time zones or several cities; at that point it's not that the weekend was too short, it's that the itinerary was sized for a much longer trip.
What about a work trip with a few extra days tacked on — does that count?
Only if the extra days actually get treated like the trip, not squeezed around meetings as an afterthought. If you're still half in work mode for the added days, they don't function as a buffer or as rest — they're just work with worse boundaries.
I only have limited PTO left this year — what's the minimum that's still worth it?
Match the trip's scope to the days you actually have, rather than stretching a big trip into too few of them. A well-scoped weekend or single-destination trip within a smaller time-zone jump will beat an ambitious multi-city trip crammed into the same number of days, every time — see the table above for what actually fits your window.
