DO NOT Trust Lufthansa With Pet Medication!!!
Long story short, we had to fly our epileptic dog from the US to Europe, and went out of our way to use Lufthansa because they have the "animal lounge" in Frankfurt for the layover. Our dog hasn't had any seizure in years because it's controlled by medicine, given every 12 hours. We were told multiple times by Lufthansa before and during booking that they have no problem administering the medicine at the animal lounge during her layover, and that they even have vets on-site to do it. We timed the route correctly so they could do this.
We put the medicine in a super obvious, clearly marked bag with a large sign with very simple instructions for the Lufthansa animal lounge staff to see. If anyone even walked by her crate, you would immediately see it, we made it unmissable.
When we retrieved our dog from the destination airport, we discovered NONE of her medication was given to her.
DO NOT TRUST LUFTHANSA WITH ANY PETS THAT REQUIRE MEDICATION, EVEN IF THEY REPEATEDLY CONFIRM THEY'LL DO IT. We are beyond angry, this was a simple request that they told us they do. If they aren't going to administer the medicine at the lounge, they should have just told us. They made it seem that there was NO DOUBT their staff would do it.
I did reach out to them and they repeatedly sent back automatic messages about medications not being allowed in carry-ons, showing they didn't even bother reading the message at all.
