Business/PE Light comes to US flights
AFKL-marketed/ticketed flights on AFKL metal commencing outside the US (except LON and MAN, presumably waiting on VS for those markets) now offer Business Light: 500 euro change fee, no lounge access, 1 checked bag, and seat selection only becomes free at check-in. Elites (including STE) get free standard seat selection and STE+ get lounge access.
Fare differential from Standard (effectively the second checked bag, free seat selection on this route thanks to the JV, lounge access if not elite, and a 200 euro reduction in change fee) is ~$130 each way
This feels likely to be the template for D1 Light: no D1 lounge access at all, no SkyClub access except for STE+, seats for non-elites only become free at check-in, and a $500-ish change fee.
