Shipping Eggs: Express Worth It?

[altair]

I've only ordered shipped eggs once and got 3 robust chicks from 8 eggs. I'm pondering paying extra for quicker shipping for (hopefully) better results.

Is there anyone who's paid for faster shipping and noticed better hatching results from it?

I think travel in the un-pressurized cargo-hold of an airplane probably damages air cells and egg contents more than ground travel. If faster delivery means air travel, it may actually increase the risk of damaging egg contents.

Valid points! I was just looking for someone who'd done both--or at least express--and shared their hatch rate. It's likely negligible I think.
