**You can use your recently expired passport for this domestic flight.** TSA currently accepts the passports on its approved ID list—including U.S. and foreign government passports—for **up to two years after expiration**. If yours expires between now and your trip, it falls within that window. Bring the physical passport. [TSA identification rules](https://www.tsa.gov/travel/security-screening/identification)

For getting a replacement within two weeks:

- **California ID:** Apply for a **REAL ID** if you want to use it for flights. California DMV says a new card arrives by mail within **three to four weeks**, so you should not count on receiving it before this trip. A standard California ID does not meet the current flight ID requirement. [California DMV](https://www.dmv.ca.gov/portal/driver-licenses-identification-cards/identification-id-cards/)
- **U.S. passport renewal:** Expedited processing currently takes **two to three weeks, plus mailing time**. Faster passport agency appointments require proof of **international travel within 14 days**; your domestic flight alone does not qualify. [State Department processing times](https://travel.state.gov/en/passports/apply/help/processing-time.html)

For your upcoming trip, keep your current passport available and renew it afterward. These expiration rules apply to TSA screening for domestic travel; international travel has different requirements.
