We booked JAL ORD-HND on CX. However, because CX membership sign up page did not have option to input suffix after last name, my husband's JAL booking does not include his suffix "III". His name on his passport John Doe III. The JAL booking shows John Doe. Googled and some say the suffix doesn't matter but there are anecdotal stories of someone with missing/misspelled middle names being denied boarding. I will try to get it corrected via CX but I worry that if that involves cancelling and rebooking, we may lose the award space. (And it will cost us $240 as it was two separate bookings for outbound and inbound flights). Is missing suffix a non-issue as some say? Or do I need to try to get it fixed? Any insight is appreciated!
