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.
Schema
The services that can be booked along with the offer but are not included by default, for example an additional checked bag. This field is only returned in the Get single offer endpoint. When there are no services available, or we don't support services for the airline, this list will be empty. If you want to know which airlines we support services for, please get in touch with the Duffel support team at help@duffel.com.
The currency of the base_amount
, as an ISO 4217 currency code.
It will match your organisation's billing currency unless you’re using Duffel as an accredited IATA agent, in which case it will be in the currency provided by the airline (which will usually be based on the country where your IATA agency is registered).
"GBP"
The conditions associated with this offer, describing the kinds of modifications you can make post-booking and any penalties that will apply to those modifications.
This information assumes the condition is applied to all of the slices and passengers associated with this offer - for information at the slice level (e.g. "what happens if I just want to change the first slice?") refer to the slices
.
If a particular kind of modification is allowed, you may not always be able to take action through the Duffel API. In some cases, you may need to contact the Duffel support team or the airline directly.
The ISO 8601 datetime expiry of the offer before which the traveller should use this offer to create an order. After this time the offer can no longer be used to create an order.
"2020-01-17T10:42:14.545Z"
Partial offers are a new concept we're introducing as a part of a new multi-step search flow that we're currently experimenting with.
A partial offer can't be booked directly, but it can be combined with other partial offers to form a full offer.
Partial offers are only ever returned through the multi-step search flow. So there's no need to add any handling to deal with partial offers if you're using the traditional OfferRequest
search flow to create offers.
true
The slices that make up this offer. Each slice will include one or more segments, the specific flights that the airline is offering to take the passengers from the slice's origin

A list of airline IATA codes whose loyalty programmes are supported when booking the offer.
Loyalty programmes present within the offer passengers that are not present in this field shall be ignored at booking.
If this is an empty list ([]
), no loyalty programmes are supported for the offer and shall be ignored if provided.

List offers
Retrieves a list of offers for a given offer request specified by its ID. Unless you specify a sort
parameter, the results may be returned in any order.
This endpoint does not return the complete, up-to-date information on each offer. The Get a single offer endpoint should be called for a given offer in order to get complete and up-to-date information.
Query parameters
A cursor pointing to the previous page of records. For more information on how to paginate through records, see the Pagination section.
"g2wAAAACbQAAABBBZXJvbWlzdC1LaGFya2l2bQAAAB="
A cursor pointing to the next page of records. For more information on how to paginate through records, see the Pagination section.
"g2wAAAACbQAAABBBZXJvbWlzdC1LaGFya2l2bQAAAB="
The maximum number of records to return per page. Defaults to 50
.
May be set to any integer between 1
and 200

By default, the offers will be returned sorted by ID in ascending order.
This parameter allows you to sort the list of offers by total_amount
or total_duration
.
By default the sorting order will be ascending, if you wish to sort in descending order a -
will need to be
prepended to the sorting attribute (i.e: -total_amount
).

Get a single offer
You should use this API to get the complete, up-to-date information about an offer. This endpoint does not guarantee that the offer will be available at the time of booking.
Due to limitations in airlines' systems, you may see changes to the offer (e.g a changed total_amount
).
Additionally, you may receive information that may have not been included in the original offer such as baggage allowances.
Optionally, you can request information about additional available_services
that you can book
with this offer by specifying the return_available_services
query parameter. Each time you make this API call there's
a possibility that some of the service information will have changed, so you should always use data (e.g prices, service IDs)
from the latest call to this endpoint when booking an offer.
