I've flown a few times so far in 2024 and overall, security lines have become a lot longer than pre-COVID. More often than not, they stretched all the way to the air-side entry gates although they kept moving steadily. I think taking 20 minutes to get this part done is reasonably optimistic. I generally arrive at the airport 90 minutes before departure now even with a mobile boarding pass just in case. I've done 60 minutes before and it was a bit of a dash to my 2xx-gate.
