How much the order matters here

Getting the order right is worth $160 a person on this trip, 15% of what the cheapest way round costs. Of the 72 trips we price in full, that is number 58 for how much the order matters, one of the smaller gaps: on this trip your dates are likely to matter more than the order.

What these numbers are

Cached one-way fares, 12 of 12 legs priced from real observations, put together on October 29, 2026, from fares departing October 29, 2026 onwards. Right for comparing one order with another, not a quote for your dates.

A plan prices your own dates and weighs hours as well as fares, so it can pick a different order from this page.
