How we estimated this

A planning estimate, not a live quote. Per-diem covers meals & incidentals; the hotel line covers lodging, they don't overlap.

FAQ

What does the trip estimate include?

Flights, hotel, per-diem meals and any extras you tick (airport transfers, travel insurance, eSIM, visa), itemised into a single planning range.

Can I estimate a multi-city trip?

Yes. Add each stop with its own nights using Add a stop; flights are summed segment by segment, and hotels and per-diems are calculated per city. Return to origin adds the flight home.

How are flight costs estimated?

By a distance model: each segment's great-circle distance times a per-km rate (economy anchored on BTS/MIT passenger yields, business roughly three to four times per IATA), sanity-checked against the CWT-GBTA 2026 forecast. It is an indicative range, not a live fare.

Are these live, bookable prices?

No. Flights use the cited distance model and hotels use an indicative average daily rate. Live, bookable prices come from Accomy.

What is the difference between this and the Per Diem calculator?

The Per Diem calculator gives the daily meals-and-lodging allowance for a city. The Trip Estimator gives the whole trip budget, flights plus hotel plus per-diem plus extras, itemised into one number.

How accurate is the estimate?

It is a plus/minus 25% planning range, not a quote. Every assumption is shown on screen and can be edited to your own figures.
