As long as the guy is 63.5 or 64..I knew one guy that was 64 and straight up said he just wanted a year as an airline pilot for a year and was on his bucket list his entire life. Some companies might not hire someone that age but others are hurting for pilots. Not sure if he ever made it through training but he was initially hired I believe at Xjt.
Tell your friend all they can say is no. It’s worth the shot!
