What is the difference between PCS and TDY in terms of travel pay?

• A. PCS is permanent relocation with long-term entitlements; TDY is temporary travel with per diem and mileage allowances
• B. TDY is permanent relocation with long-term entitlements; PCS is temporary travel with per diem and mileage allowances
• C. PCS has no allowances; TDY has housing allowance
• D. PCS and TDY are identical

Answer: (B)

The key idea is that travel pay differentiates a permanent relocation from temporary travel. Permanent Change of Station means you’re moving to a new duty location with long-term entitlements tied to that move—relocation allowances and benefits that support settling in. Temporary Duty travel, on the other hand, is a short-term trip where you receive per diem to cover lodging, meals, and incidental expenses, plus mileage allowances if you use a privately owned vehicle. So the description that PCS involves long-term relocation entitlements and TDY involves temporary travel with per diem and mileage allowances best captures how the pay is structured. The notion that TDY is permanent relocation, or that PCS has no allowances, or that the two are identical, doesn’t fit how these programs operate.
