The Department recently announced that effective April 7, 2022, the Joint Travel Regulations (JTR) allows nursing service members and civilian employees to be reimbursed for shipment of breast milk when on official travel for more than three days.
The Joint Travel Regulations were revised to specify that the cost of shipping breast milk may be reimbursed as a travel accommodation for a special need during temporary duty (TDY) travel. Authorized expenses may include reasonable commercial shipping fees, excess baggage, disposable storage bags or non-durable containers, cold shipping packages, refrigeration, and transport.
The memorandum for the Joint Travel Regulations revision can be found here.
