We've released support for ancillary bags in the Duffel API. For some offers we now return a list of
available_services, like extra baggages, that can be booked along with the offer.
We are releasing this feature for British Airways and Vueling to start and will be adding support for more airlines in the future. If you are interested in a specific airline, please let us know at email@example.com.
To make the integration of this new feature as smooth as possible we've written a step by step guide on how it works. We've also updated our API documentation to reflect the API changes.
