Unfortunately my last two flights on my six aircraft trip will be on the A321T (BOS-JFK-SFO) and applying a SWU isn't available.
Hoping my upgrade trend holds true as I've gotten all upgrades possible thus far. At the moment, the AA seat map, when I'm not logged in, shows J sold out for both legs. But when I log in, and since I selected a seat in J for BOS-JFK (which is Y on this flight), there are seats available. Clearly AA is blocking what's viewable.
Regardless of what the outcome is, I still look forward to being on this aircraft as it would be a first for me. I tend to make my entrances/exits on the east cost scene via PHL, BOS or CTL. This time around, I opted to try something different.
