While I have not used Delta Dash.. it seems to be the shipper of choice for more expensive animals. Being shipped airport to airport skips the risky bumping along in a delivery truck phase.. and potentially being in a very cold or hot environment for extended periods of time.

It's one downside (though minor really) is the increased cost of the service.. I believe you must be certified to ship live reptiles through delta dash too (much like Fedex)
