This doesn’t appear to be targeted.
It’s already possible to buy status on US Airways. They sell PQMs to members, though it can be a bit pricey. Although, based on the price of the shuttle, it’s probably cheaper to just buy the PQMs than to mileage run.
At any rate, though, it’s worth registering for this offer if you live in the Northeast. I don’t value US Airways status too highly, but some status beats no status at all.
