It has become the airlines that cater to dogs better than they do people. I have severe allergies to pets. I don't mind changing my flight for a real service animal but it has become a fad to get a small dog and call it a service animal. Every month I take a flight and every month it have to change my flights due to "service animals" on the plane. People with pets are not required to inform the airlines in advance that they will be traveling with pets. So I end up being delayed (24 hours so far this time), Every flight today had pets. It triggers inflammation in my airways. It's not a matter of sneezing. When I book my flight I inform them that I need a wheelchair to get to the gate, why can't people inform the airlines when traveling with pets. We are crammed in like cattle and now we people have to share the air and small space with animals.
