Cons: FedEx doesn't have control over the shipment, cost.
FedEx Same Day service is their answer to all of the local couriers that you can find in the Yellow Pages. The huge price that you pay for the service is not worth the extra cash it will cost you.
Packages are picked up at any time, and depending on when it is picked up will go on the next flight they can find. This means it is not handled by a FedEx driver, and is not on a FedEx plane. Yes, that is right it is totally out of their hands. You just as well could have thrown it on the flight yourself. When you fill out the FedEx airbill, it could actually be flying on Delta, Southwest, or United. This does not decrease your chance of it getting there, but it does mean they are out of control.
If you have a question on where your package is, they cannot tell you. If the other airline loses it, FedEx cannot fix the problem. They do have great customer service, but unfortunately this service cannot do anything for you. I recommend most FedEx services as the best, but Same Day really is not your best option. You might as well spend eighty or ninety dollars less and hire a local company to take care of it. From my experience using this service, it seems that you are really paying foe the FedEx name instead of the service you are getting.
The times my company has used this service, it has never turned out as good as they make it seem. UPS's service that is similar is a little better, you might want to check them out.
