I was able to check-in T-24 on JALs OLCI via my web browser for my flight tomorrow (AA F award flight LAX-NRT-BKK) and received "print at home" boarding passes for both flights (also was able to add them to my apple wallet). I had the understanding that it wasn't possible to get boarding passes without document check at the JAL ticketing counter, and it's been that way with AA/BA check-in over the last 1.5 years. I guess that's changed now, or as it always been that way during COVID?
