I think what some people here are missing is that you'd have to meet the UK's rules in addition to the AF's. Customs doesn't give a shit about the vol 3. PCSing to/from OCONUS with pets is usually a nightmare, but they're worth it. Dude with the epic dog needs to get started on this shit about 6 months ago. I'd recommend talking to TMO to see who has the contract to fly you overseas, check out that Airline's pet policy, then take circuitous travel rather than hoping you get 1 of the 6 pet spots on the Patriot Express. Alternatively, start the paperwork for the dog and hire someone to fly it to England. I ended up having to pay someone to fly my dog out of Japan because TMO fucked up my travel request.
