How to Plan a Multi-City Trip
A good multi-city itinerary balances airfare with the time spent in each city. The cheapest individual leg does not always produce the cheapest or most usable complete trip.
Choose the cities and the true start point
Use the airport from which the whole trip begins as the start city. Then add the places you actually want to visit, not connection airports that merely appear in a fare.
Three or four cities are usually enough for a meaningful comparison without turning the trip into a sequence of airport days.
Decide whether the route closes into a ring
A return-to-start route ends at the original airport. An open route finishes in the final city, which can be useful if you continue by train or have a separate onward journey.
Compare both structures when possible. Returning to the start can simplify the booking, while an open route can remove backtracking.
Distribute nights before optimising price
Set the total nights and minimum stays that make each city worthwhile. A mathematically cheap route is not useful if it leaves only a few hours in the destination you care about most.
Overnight flights may extend the calendar span without adding a hotel night. Check arrival times when interpreting the suggested distribution.
Verify every ticket and connection
Multi-city results can contain separately booked flights. Confirm baggage handling, terminal changes, visa requirements and enough buffer between independent tickets.
The planner compares available legs; it does not guarantee that separate bookings are protected if an earlier flight is delayed.
Compare the options that fit your trip
