I believe that I heard that the US Mail started putting their mail back on commercial flights over the weekend. With the backlog though it might take some time to catch up. Also consider that airplanes can only take so much mail along with other cargo, passengers and luggage etc. and with many airlines cutting flights by say 20% it might take a little longer to get back to normal. I am still waiting for a chip from LA. The seller put feedback on my eBay on the 12th. I assume it was sent on or before that date. I would expect that maybe it will still take a few days. Unless it was trucked back then.
