First time coming up flying business on CX, solo traveller. First leg is on A350-1000 (16.5 hour flight time) and second is on A350-900 (9.5 hour flight time). I'd really love a window seat, but I'm not sure I understand the priority seats and if there's a possibility I could lose my business class seat if someone else needs that priority seat? The first flight, I'm in 14G, there are other non-window seats further back, but 23K is also open. SImilarly on the second leg, I'm in 18G but 20K is open. Am I also likely overthinking the privacy of the G seats?
On my return flights, there's nearly full window availability on the first leg, so right now I've got 15A on the 350-900 and the second leg I have 22A on the 350-1000
