41 CFR 302-4.1: -4.1 Eligibility for subsistence and transportation allowances for permanent change of station (PCS) travel.

Employees are eligible for subsistence and transportation allowances for PCS travel if their agency specifically authorizes relocation expenses under this part. Except as specifically provided in § 302-5.6 of this subchapter, the rules (for TDY travel) in chapter 301 of this subtitle will be used for payment of the travel expenses of the employee's immediate family members. If an alternate location for beginning or ending PCS is used, reimbursement is limited to the allowable cost by the usually traveled route between the old and new official stations. An attendant may be authorized to accompany an employee with a special need in accordance with § 301-13.2(a) and (g) of this subtitle.
