This is a routine issue worldwide. Terms such as "first name" and "Last name" mean different things in different places. So long as all of the names used on the ticket appear in some order on the passport, you won't have any problems. Thus, if your passport is "A B C" and your ticket is "B C" or "C A" there won't be an issue.

Where problems arise is where names on the ticket do not appear on the passport, e.g. passport is "A B C" and ticket is "D C".

Nonetheless, as a tip for ease of travel, in future, make certain that all documents match exactly.
