Common questions

Which airports have cheap flights to London Heathrow?
We are currently tracking 74 fares into London Heathrow from 32 departure airports, listed cheapest first above.

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.
