Pet Carrier

What kind of cage is best for the planes?
I'm bringing my cat with me to my parents for Christmas. The airline requires 37.5 "size total (8.5 "high x 17" long x 12 "wide). I'm looking for carriers rolling book bag in front of just the sort of bag canvas. Any suggestions on what kind of transportation is best for flying?
I assume that you are taking the cat on board as hand luggage. Most the airlines require that your pet will be placed in an approved soft-sided kennel that has one or more parts mesh and an absorbent leak-proof bottom. Also, make sure the plane is flying with not having a limit in kennels that can be taken on board as hand luggage, so if it is the case, the book of the kennel in advance to avoid disappointment. The airline I work for allows a maximum of 4 bags from the pound and 4 kennels check on each flight.
