Hey Coach! How long ago? Pet safe is what we are going through and on their website if the dog is a bully breed or a bully mix they require a reinforced crate.
Continental is now United and although they allow them, they are required to be in "stronger" crates.
Select dog breeds as mentioned on the Pet Restrictions page require a reinforced crate. IATA Container Requirement #82 states that the container or crate must be constructed of wood, metal, synthetic materials, weld mesh or wire mesh. Additional design principles regarding frame, sides, floor, roof and doors also apply. No portion of the crate can be plastic. The crate door must be made of heavy wire mesh, metal or reinforced wood and should have a secure means of fastening that cannot be opened accidentally."
That's from the website.
when I look up these crates they cost any where from $500 to $800.
