I have said this before and I will say it again. They worry about peanuts while severe asthmatics can die from a cat on the plane. My son has been on a respirator from a cat. He is on a trip to Hawaii now and I am worried sick there might be a cat on one of his flights. If enought people with allergies to animals formed a cohesive group to negotiate with the airlines it might hold more weight. While they won't stop letting animals on flights, all I ask if that they have at least one flight a day that has no animals on it. I don't think that is unreasonable. I have written to the airlines several years ago but to no avail. I think you need to gather a large group of flyers to accomplish anything. And yes, you can ask at the gate, but then it's too late to do anything about it.
