# Offers

After you've searched for flights by creating an offer request, we'll send your search to a range of airlines, which may return offers.

Each offer represents flights you can buy from an airline at a particular price that meet your search criteria.

You'll see slices inside the offers. Each slice will also include a list of one or more specific flights (called segments) that the airline is offering to get the passengers where they want to go.

An offer is only available to create an order for a limited time by the traveller before it expires, typically within 30 minutes. Exact time is indicated by the `expires_at` field.
