Capabilities

Tools 3

get_deal

One Sparkflights fare by the numeric id from search_deals: its itinerary, the price text of its fare page, its outbound and return flights, the date pairs its fare page lists with their prices, and its url, route_url and feed_url. A fare that is no longer live returns an error naming its route page.

Discovered
search_deals

Search the current flight fares on Sparkflights, ranked by cost per mile against each market's limit. Each deal is available now and shows when its price was last checked; an empty result means no current fare matches, not that no flights exist. Each deal has the price text of its Sparkflights fare page; url, the fare page; route_url, the route page, which lists the route's live fares and price history; and feed_url, the route's JSON feed of new fares. A search naming an origin or destination also returns fares when its deals are fewer than limit: the cheapest current fares for that place, each with its price, dates, airline, seen_at (when it was seen) and route_url, its route page. A fare has no id or fare page yet.

Discovered
watch_route

The Sparkflights page that saves a fare watch for a route: url opens the watch form with both cities and the cabin filled in. A watch covers every airport of both cities. Saving it needs a free Sparkflights account.
