I’m also posting just I case anyone else was looking for answers!
I ordered the 13 inch MacBook Air with 8GB memory + 512GB storage and two engraved AirPod pros on Sunday, August 9.
The AirPods shipped out Tuesday, August 11. Estimated shipping according to FedEx is Monday, August 17. So I should be receiving them in a few days & it is a little earlier than what Apple estimated in their email (August 20-24).
My MacBook didn’t ship out until Thursday, August 13, but it arrived the following day due to next day shipping. It shipped from somewhere in Southern California, about an hour and a half away from me.
My AirPods did go through customs and luckily for me, they didn’t get stuck for too long. I’d say about two days!
