I Love Riley's Kwigy Bo bags.. He has 2... He Loves them as well.
He just Looooves being carried...!
I thought about using one of them for the plane but then when I saw
the sturdibag I liked how you could squish it down under any seat. It
has two tent rods so that the bag completely pops back up to give the
pup the most room they can get under the seat.
