I don't want to be insensitive, but pets should not be allowed to travel in the main cabin due to so many allergies these days. Paying customers have an expectation of relatively clean aircraft and ok service. Paying passengers Gould not have to be subject to pet dander in close quarters. Those that bring their pets on board who have issue with this have little respect for their fellow travelers. I need to qualify this statement by mentioning that I am an owner of 2 cats and would never travel in the main cabin with animals. It's disrespectful to fellow travelers.
