Why would the FAA hire people, pay them move money, send them to OKC and have them sitting around waiting indefinitely in Philly for an airspace move that could continue to be delayed all while they could continue working traffic and providing staffing where they're at. And when everyone gets there at the same time and creates super long training backlogs, they're going to have the same problems n90 currently has where people really need to go back to okc for a refresher or similar issues. My guess is they'd start sending out offers in Jan or Feb '22 assuming that the end of summer date for the airspace move holds strong. That gives them enough time to allow for the 3 month release from the current facility, request a tsew/tetra date, spend 2 months in okc for said classes, and then come back to PHL and do class and sims. Moving anyone before that makes 0 sense, so you can expect your offer to be in your mailbox by the end of the day tomorrow.
