No simple crate will do. For instance, when I worked at teh airline, thecrate had to be of a certain certified type, non collapsible, and big enough for teh animal to turn around. Furthermore, teh screws have to be adjusted backwads, meaning you can easily spot if one comes loose and hence tehre is a risk of the pet coming out. I remember having to rememove the screws many time sfrom crates and placing them the airline way at the counter right before checking in...
I'd reccomend going to one of the big stores in Keelung (Jilong) road -I remember places like Royal Cat and Pet Garden having a selection of airline approved crates. Also, Top Vet had some last time I was there, smaller ones, suitable for cats.
Remember you have to "book" your pet on the flight -only so many pets allowed per flight- and check the dates -sometimes depending on weather conditions, no pets are allowed in the cargo hold.
