My passport expires on February 2022, but my vacation will on?
Are you a US citizen? If so - you can renew your passport any time you want. While uncommon, you could even get a new passport - and apply for a new one the next day. As long as you submit the previous passport with your DS-82 . . . whos going to disagree with you ? However, if you were to get a new passport, and then report it lost the very next day, and hence apply for a new one . . . that may raise some eyebrows. Bottom line: renew it now.
