Common questions

How cheap can flights from Seattle to Rome Fiumicino get?
The cheapest fare we have tracked on this route is $291, compared with a typical $761 for a trip of this distance.
Is it cheaper to fly to Rome Fiumicino from a different airport?
Often, yes. Fares out of secondary airports are frequently cheaper than the obvious hub, but they are the ones most likely to be missing from a normal search. Our reverse search compares every airport in a region against each other so the cheaper departure point is not hidden.
Could a stopover make Seattle to Rome Fiumicino cheaper?
Sometimes. On thin long-haul routes a two-leg trip with a multi-day stopover can beat the direct fare, and occasionally a direct fare is not sold at all. Our detour search prices those routings against the direct flight.
