It's Passport Awareness Month, and the U.S. State Department has this advice: renew your passport before 2018.
It's the off-season for passport renewals. Wait times increase in January through the summer.
The State Department said it expects to see 20 million passport applications for fiscal year 2017.
New passport books for adults start at $135. Renewals for a passport book start at $110. You can also add expedited processing and faster shipping for additional fees.

REAL ID information
The State Department reminds travelers that passports meet REAL ID requirements for domestic air travel.
The REAL ID Act requires driver's licenses to have certain security features to be accepted as identification at TSA checkpoints.
Arizona driver's licenses issued before April 2016 do not meet those guidelines, but Arizona was granted an extension until Oct. 1, 2020. Any Arizona driver's license will be accepted until that date.
Make sure to get a new ID before then.
