A big airline is relaxing its pet policy to let owners bring the companion and a rolling carry-on

American Airlines is relaxing part of its pet policy to let owners bring their companion and a full-size carry-on bag into the cabin...

Until this week, people who carried a pet into the cabin - which involves paying a $150 fee - could only have one other small item that fit under the seat...

Anything bigger, like a carry-on bag with wheels, needed to be checked - for a $35 fee..

Now American is letting passengers bring a pet in the cabin and also bring a regular carry-on bag or a personal item - just not both bags...

Leff said he thinks American's change will reduce the urge for travelers to falsely claim that their pet is a service animal that flies for free...
