Error when entering API
Hi everyone. I'm trying to add my Advanced Passenger Information (API) in advance of a future flight on the Swiss website and I'm getting the following message:
Sorry, this flexibility is not supported. Please refine your search criteria. (DAPI/400/4926)
I've tried this via the Lufthansa website too but as all the backend systems are now shared I get the same error message. Lufthansa Group IT gremlins at work? It's no big issue - just was hoping to save some time when online check-in opens.
Any ideas?

Hi - I managed to get all API updated on the Miles & More website. Logged in with my Miles & More account, went to manage booking and the followed the link to Immigration Details.
I wonder if that works for you? Good luck and enjoy your flight later.

It seems like the drop down to select "document type" under the KTN heading will not let me select a document type--and it is a starred field meaning it is required to make a selection. I think this is the thing that keeps giving me errors. I called customer service last week and the agent acted like it was no big deal that it wasn't letting me put the info in and save it. Because of the error, the website and app will not permit saving of any API. So frustrated, because it also looks like I will be dealing with this winter storm and the knock-on effects of it. UGH!

Anybody else have issues with entering API data on swiss.com?
i habe a flight to CLT end of March, ex MUC, and another to DEN in September ex ZRH.
One ticket is an award in C, the other paid in C.
on both reservations it states, that once I‘m checked-in I cannot change online, but need to call.
weird….
