833-861-7710 is who I called when I flew with my cat for the first time. I was nervous about the rules—carrier size, fees, in-cabin vs. cargo, all of it. The agent walked me through everything: pet reservations, weight limits, and which aircraft allowed in-cabin pets. They even checked which flights had available pet spots since space is limited. Having someone patiently explain each step calmed me down so much. If you’re traveling with a pet, this is the easiest way to make sure nothing gets overlooked.
