Missing seat designator from OrderSegment passenger

[Tom-Carpendale]

The Duffel docs describe how you can access a passengers seat designator from the passengers on the segments, however I am finding that even when the service is present in the create order response and has the relevant Ids for the segment and passenger, the seat field on the passenger is null.

Thanks!

Hi, sorry for the lack of response here. Are you still seeing this issue?

[Tom-Carpendale]

Hi, yes, I am still seeing this using Duffel 3.1.0.

[danielgreening]

Hi @Tom-Carpendale 👋 thank you for reporting this!

This is a bug on the API side, we expect this field to populated if the service has been confirmed by the airline. We've created a ticket with the relevant team to get this addressed. We'll update here when the fix is out 👍
