Common questions

Which airports have cheap flights to Ottawa?
We are currently tracking 23 fares into Ottawa from 6 departure airports, listed cheapest first above.
Is Ottawa the cheapest airport for this trip?
Not always. Cached fare feeds cover big hubs densely and secondary airports sparsely, so a cheaper nearby airport is often simply missing from a normal search rather than more expensive. Our reverse search prices a whole region's airports against each other to surface it.
