How the Fairfax rate is used
TDY. Lodging is reimbursed at what you actually pay, up to $276 a night; M&IE is $92 a day, paid at 75% on the first and last day (JTR par. 020302). If a government meal is provided, the proportional meal rate ($41) replaces full M&IE.
PCS — Temporary Lodging Expense. TLE for a move to or from Fairfax is built on these two figures times a family percentage, capped per day (JTR par. 0506). The TLE calculator already knows this locality — search it by name.
PCS — driving days. Travel days by POV are paid the flat standard CONUS per diem ($178), not the locality rate — see the MALT + per diem calculator.
