I also agree Airborne isn't the greatest. How much is UPS or FedEx? Probably too much overseas I assume.
FWIW, Airborne was recently bought by DHL.
My experience shipping (was before airborne was bought, though):
I used to ship small <1 lb to 5 pound packages for work. Airborne was the cheapest, UPS next, and FedEx the most expensive for these sizes shipping within the US. Most customers wanted UPS, which cost them $15 for a $10 item (airborne ~$10, fedex ~$18). We got delivery complaints in a far higher pecentage of the UPS shipped orders than airborne orders. UPS then hiked the shipping prices for us, so we dropped using UPS, and our total delivery complaints dropped.
My experience receiving, both personal and at work:
Airborne. No problems.
UPS: one major problem, a few minor. The major problem: one shipment was 2 business days late + a three day weekend because it went, after correctly arriving to the hub that deliveres to me, to another nearby hub, back to my hub, and then delivered to me. Five days late!
FedEx: three problems. Most recent (approx. a month ago), an shippment was 2 days late because it got "lost in a truck". Tracking said it was in a truck for delivery on the due date, but never delivered. No change the next day in tracking except the expected date was, of course, one day after the original date. Still nothing. Next day, tracking said it was put in a "truck for delivery" again, and finally I received it.
FWIW, all three would leave a note if no one was at work, but leave the package at the door at home. I here it varies from neighborhood to neighborhood albout leaving the package at the door.
My personal shipping preferences: USPS priority mail, airborne, UPS, snail mail, fedex, in that order from most to least.
My two cents.
