You've given no info on seniority/fleet/rank. Assuming it's 380. I have never got a US trip via preferences on the new system even bidding USA. It's crap. Have got a LA trip once only a request in top bid and seniority below 100. Never had an issue on the old system.. go figure! Meanwhile I see fairly new joiners going to all the best destinations regularly..
Before anyone asks, CRS guys said it's been fairly similar for everyone
