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 30, 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.
