Can anyone tell me the difference in products comparing the two in each cabin class. Thank you
beware that in KL offering , there is premium economy and economy comfort
as far as i know the premium economy also called premium comfort is not yet deployed on all KL planes
also seats are not the same in J across all planes , for both KL and AF , so as your question is super wide i would recommand this website =
https://flight-report.com/en/search/
it will give you an overview about what to expect, and because this site is bilingual (english + french) , if route/plane you wanna check is in french you can use autotranslate function of your webbrowser
