i have a chihuahua...and I flew from fort smith, arkansas to fort lauderdale, florida and daisy had no problems what so ever....she would let out a bark when we took off...but other than that no problem!!

I have a little carrier that I put her in and keep her with me...as my carry on luggage...when the plane takes off you put the carrier under the seat in front of you and sometimes when you get to cruising level they will let you take them out.
