Then again, sometimes we just have to suck it up and deal with it, and hope the airline staff can do what they can to separate the animals from the people with allergies as much as possible. While there are certainly some people who bizarrely can't go anywhere without their pet (and I personally don't care if we don't make accommodations for them), but people do legitimately need to travel with their pet sometimes, and we need safe ways to do that. We have two cats, and if we were to move to somewhere far enough away that driving were infeasible, I would want to travel with them in-cabin.
