CHICAGO (AP) — More and more airlines are saying “No” to emotional-support animals. United Airlines is the latest. United announced Friday that starting with flights in February it will no longer accept emotional-support animals. It will let trained service dogs fly for free in the cabin, but owners of other animals will have to pay a pet fee to put them in the cargo hold or a carrier that fits under a seat. Alaska, American and Delta have announced similar changes. The airline moves come after the Transportation Department allowed them to crack down on the growing number of emotional-support animals on planes.
