Common questions

Where can I fly cheaply from St Louis?
We are currently tracking 56 fares out of St Louis across 39 destinations, listed cheapest first above.
Is St Louis 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.
