Day 13 for you, and 12 for me.
In the grand scheme of things, it's not actually a big deal. We'll eventually get those points one way or another. However, it puzzles me how this happens. With e-ticketing and on-board scanning, the entire process should be automated. Once the ticket is electronically lifted, the record would be updated. Then, maybe each evening, a process would take all those lifted records, throw them over the fence to AGR, which then processes the records and posts the points - once again fully automated. Since the Monday (1/19) trips have posted, it seems like the 1/16, 17 and 18 records either never got thrown over the fence to AGR, or AGR got them and they have been sitting in some electronic limbo somewhere.
In the olden days of paper coupons, missing flight miles were common. That disappeared maybe 20 years ago with airline e-ticketing. Air miles posting is now fast and reliable. With US Airways, it takes two days for miles to appear following trips - without fail. Now that Amtrak has caught up electronically, I cannot understand how this kind of delay occurs.
