If you are flying BA, then you will be OK with NOT having the APHIS 7001 form which is the International Health Certificate. Some airlines may require it, but BA only needs a standard letter from the vet stating that the animals are healthy enough to fly (so I was told by BA when I booked the reservation for my pets).
You only need the APHIS 7001 for the airline if they request it. The UK will not see this document, and they will not even care about it
Mirrajay.....I still need to get the EC 998 form endorsed by the USDA. I called them about 8 weeks back to make an appointment for the EC 998. They told me to wait until I was within the 10 days of leaving because they would also endorse the APHIS 7001 form at the same time. I thought that I needed the APHIS 7001 form at that time, and you need to do this form within 10 days of your flight. The reason why they told me to wait is because they charge $119.00 for each visit (just for paperwork endorsement). This way I would just have the one visit instead of two. Now, I know that I do not need the APHIS 7001 form, but I will have the USDA endorse it anyway since I have it. I have my appointment this Monday. I am going to the USDA that is located in Richmond, Va.
One of the main reasons why my APHIS 7001 form was so expensive from my vet is because of the health exams (not because of fees for filling out the forms). I have three animals, and they charge extra for this type of an exam fee. I think that I got a bit stiffed on the fees because their normal exam charge is $39.00 an animal, and they certainly did nothing extra with this. I have not been happy with this vet since we started the quarantine. They are very nice, but their fees (I feel) have been excessive. There was nothing complimentary with this. The vet has seen them at least three times in the last six months, and I feel now that this should have been a free-bee (they know that they are healthy).
All three animals were due for their vaccinations about 6 weeks ago. I called the vet, and I could not even slide on the $39.00 exam fee for each with this. I told them that the exam fees for all these visits were killing me, and that I needed to take them to a vaccination clinic because these fees were just getting out of line.
