You can now request search results grouped by itinerary and fare brand

We've added a view query parameter to offer request endpoints. Setting view=itineraries returns results structured as a hierarchy of slices, itineraries, and fare brands — with airlines, places, and aircraft deduplicated into shared reference maps rather than repeated inline on every segment. Responses in this shape are significantly smaller over the wire compared to the default flat list, and it's also the format required to receive split-ticket itineraries. The existing view=offers shape remains the default, so existing integrations are unaffected.

Using view=itineraries results in a median response size reduction of 75%.
