Travel agent messed up on name international?

okay I am two weeks away from traveling to cancun for a wonderful vacation and have had no problems up until this point. Have booked my vacation through bookit.com and everything seemed fine when looking at the reservation on there website. Upon entering my confirmation number for us airways I noticed my name said Lll at the end of it as I am a third. The reason i didnt see this on bookits comfirmation page is because it used all lowercases lll and made me feel that this lll was the same as a capital iii or III. What should I do?
