Shipping pet rabbit in cargo hold?

I am returning home to Singapore from Bangkok. The flight is 2hr 20min and no airline will allow her to travel with me in the cabin and I do not want to give her up. As much as all the pet forums and advice on the internet are against putting any rabbit in the cargo hold, I wonder how professional breeders do it. They can't possibly travel with the bunny each time there is a purchase right? Does anyone have the experience?
