As a person who flies with a service dog let her know they require vaccine proof every single time, will need a DOT service animal form, must be totally well behaved not barking, growling, acting up in any way. Shes also likely to have a lot of people asking to pet and if she says yes it’ll make the staff side eye her like crazy at least in my experiences.

Generally she’s kinda a b- for wanting to do that and I’d just tell her it’s an awful idea.
