When searching for winter flights in business class today I had an interesting option come up, which was BCN-HEL on AY1654 "plane and crew by Iberia", but in economy. This connecting to AY1 HEL-LAX in business. On the return both legs are in business. Is this economy seat a function of limited availability, or something else going on? This also has a 40 minute connection time in HEL on the way back which seems crazy.

Edited to add: never mind. It seems crazy because it is. Kiwi.com is spamming the Google Flights search results with nonexistent flights at lower prices that can't be booked.
