Warning, long post with lots of info:
I do not wish my experience on my worst enemy, so I am sharing the info I have found in the hopes it may help someone else. We tried to fly our dog and cat out on Tuesday, after thinking we had dotted the is and crossed the ts, but according to United, we were missing a health certificate.
We had Annev IV, as required by the UK gov't to import the dog and cat. There had been NO mention anywhere of any other health certificate. When I booked the flight, they only asked if I had the health certificate with the raised seal, endorsed by the USDA. No mention of any other type of health certificate.
After my pets were denied boarding, I contacted United's PetSafe desk, only to be told I was wrong, and I needed form 7001, NOT annex IV, and that the form 7001 had to be endorsed by the USDA.
I phoned the vet, the USDA, as well as HARC (Heathrow Animal Reception Centre). HARC will not tell you which form is the correct one unless they can see it themselves. As of this post, there is an updated Annex IV. The USDA have this on their website. The vet staff told me form 7001 is no longer endorsed by the USDA, because it is required by the airline, NOT the country the dog and cat are flying to. There is a letter from the USDA to this effect. The airlines have been informed of this, so to have encountered several United employees who do not know this is a bit scary. I even spoke to a supervisor, who refused to acknowledge that the form 7001 is only needed by the airline, and not required to be endorsed.
I will give links at the end of this post, one with the letter from the USDA showing that form 7001 does not need to be endorsed, a link to the part of the USDA website where you choose the correct health certificate based on what country you are exporting to, as well as a link to the most up to date health certificate available as of this post.
ALSO, and I think this is where pretty much EVERY airline falls short: *Pets* cannot fly into the UK in the cabin or in the hold AT ALL. Service animals travel under different rules, but I am not aware of them. Pets flying into the UK from the US have to fly as manifest cargo. So do not be fooled by airlines that say they will fly a dog or cat into the UK as excess baggage, because it simply isn't allowed.
From what we could tell, unfortunately, United is the only airline that will allow a person to book their own flight and send their own pet through their dedicated pet cargo service. All the other airlines require a third part IATA certified company to send your pets, and it can get incredibly expensive. Our dog alone was going to be $6k through a third party. It will be $1612 for him through United. Also, United do not allow you to clear customs with your pet yourself. They contract with PBS, and I am not sure of the breakdown of the fee, but for our dog and cat coming in on the earliest flight, the cost for PBS to do their part is $740. It is cheaper on flights coming in later in the day, I think the 11:20 arrival from Chicago was going to be $614. PBS will be the receiver, and part of the fee you pay to them is for the animals to clear customs, so all you have to do is pick up your pet from HARC.
Also, customs clearance takes about 4 hours when coming from the US.
HARC have been really kind and helpful. USDA were the same. United on the other hand, see you as a paycheck and don't give a crap about you. Hopefully they treat the animals better than the humans.
