I flew Lufthansa with my small dog last year and was relieved to learn they do allow pets in the cabin, even in Business Class, as long as they meet the size and carrier requirements. My pup fit under the seat, so it worked perfectly on our flight from JFK to Frankfurt. I wasn’t sure how to add her to the booking online, so I called 877-764-3622. The agent checked availability (since they only allow a limited number of pets per flight) and confirmed all the requirements like carrier size and fees. They added the pet to my reservation right away, and everything at the airport went smoothly. It made the long-haul much less stressful knowing she was right with me. If you need to instantly book, cancel, or modify a Lufthansa flight — or add extras like pets — that number is the quickest way to get it sorted.
