@Seraphin I remember this sort of being a thing in an earlier (recently) experimental release. I distinctly remember seeing if a passenger had a bag they would drop it at the scanner, and say the person behind them does not have a bag, they would run right through the metal detector before the one with a bag. I absolutely loved it because it helped tremendously with timing. Suddenly, it went back to just one passenger going through at a time, and I was upset at the reversal…
Olof, I’m indeed on default branch but my version still stays at 29.9.4 no update to .5,
so stuck with the fuel issue…
Agree. IRL 2 to 4 people are preparing to go through security by filling the tray’s with liquids, laptops, electronics, etc. The medium security checkpoints should at least handle 2 people because at the moment they are not quicker than a small checkpoint but are 2,5 times the size. So would be nice if the medium checkpoints would handle at least twice the amount from the small checkpoints.

Going by real life I’m pretty sure that Philadelphia International has roughly the equivalent 4 medium security stations per terminal. Terminal B, for instance, has 15 stands that accept nothing smaller normally than an E170 up through everything else the medium stand in the game does. I’ll have to do more research to see an average of flights per day, but today B1 had 5 flights over the course of 14 hours. So, yeah, I think that security should probably be able to handle more than they currently do.
I definitely have never done a 2:1 ratio of security to gates, and have never had an issue with passengers making it through security in time. I just fill up the space I allocated for security. I usually do the medium security checkpoints as passengers-only, and then small ones as staff-only. I will mostly max out my space with medium sized ones, and then 2-4 small ones depending on the size of the secure area/how many gates there are.

I’m the same, I tend to build more security points than I need initially, but only open them incrementally once there is demand. Think 2:1 ratio of security to gates is the most I’ve hit.
As I mentioned in the queuing thread, real world airports seem to be at a similar ratio:

There is a problem with the security checks… the staff leave the security check before the new ones arrive to continue… and ALL the line move out and miss their flights because they move to other security check
That happens, if distance is to long. If you have closer staff rooms for security staff, they will arrive bevor shift change and wait. It’s caused, as time for walking isn’t individually considered (yet?), but theres a fixed amount of time for walking.
Another problem with security check points:
Every intelligent person would change the queue. 
Reported as a bug once, can’t find the bug number though.
edit@size: If medium security checkpoints would be 6x8 tiles, instead of 8x8 tiles, five checkpoints would fit where there are four now.
I think that it should be changed so that the current staff only leave their checkpoint once the relief staff have arrived, as the same thing happens with baggage bays

I don’t think it happens like you say at baggage bays. I’d guess, it happens by accident if your staff room for ramp agents isn’t that far away.
Alpha 29.9-8 has been transitioned to the default branch with the following change log between the most recent default version.
We’ll deploy a new experimental version soon with a re-implementation of the proper aircraft path occupancy system that stopped working a while ago, but we need to test it out on the exp to see if it’s stable which is why it won’t go live as a part of this update.
Aaaaaand of course we’ll be back with more updates tomorrow… !

While they do all quene, they only board 1 person at a time, which is very slow. They only go one person onto the bus at a time
Not anymore… 
… queuing is disabled from the point after the boarding desk in the latest version.
Should also say it appears as if the stopped persons bug’s frequency is reduced but it’s not completely solved. If anyone here experiences it I’d love if you share it here so we can uncover what is going on.

Bug 10314, all my departing aircrafts’ baggage is invisible. Thought I was too zoomed out, but I zoomed in and still nothing; however, the ramp agents still follow through on the tasks and act as if they are there. (Not sure if the case is the same for arriving baggage, but it is visible in baggage claims)
@Olof, this is also the save where I mentioned my staff are leaving secure zones to go to a staff room, when they are literally walking past a secure staff room, and then go back through security for boarding.
I am also noticing a huge decrease in the efficiency of my security checkpoints. All of my security agents have 4 green bars in their skills, yet I cannot get an efficiency score above a 1.5 maybe 1.6. Massive delays now.
Just reported. I got schedule flights but they just stop landing or people coming to airport. I have it now twice in two different saved game.
I have several stands that complete boarding, and then have the plane not departing. 10320
Appointing vehicles is a mess, non of these vehicles I ever appointed to a stand.
