Ive checked my bags in for an Intl flight numerous times 35 mins before the departure time. True I did OLCI and as a Plat was able to take care of things at the BF counter
PHL was kind and took care of me my last trip out of there in March when I was less then 30 mins before flight time. I forget I was taking a couple of bags for someone since it was only a 1 nighter and spent the night in a Hotel up the road and the bags were in my trunk
