Hi,

I hope those of us who fly regularly out of ORD can help our frequent flying non-Chicagoans and point people toward the faster security checkpoints in each terminal.

I fly out of Terminal 3, which primarily serves American, and also serves Alaska, Iberia, Delta & Spirit.

There are four security checkpoints. (Other T3 fliers: Is this accurate? The map shows five, but I've only ever used four.) Facing check-in counters:
* The far left security checkpoint primarily serves the L concourse. I pass through this checkpoint so infrequently that I can't tell you how many x-rays there are.
* The second (third?) checkpoint from the left is reserved for elite/first class passengers. It's located between the L & K/H concourses. From memory, this checkpoint has two or three x-ray machines.
* The second checkpoint from the right is the "main" checkpoint. It's the biggest but also the busiest checkpoint. It's located adjacent to the K/H concourse. There is an elite bypass lane. I pass through this checkpoint so infrequently that I can't tell you how many x-rays there are.
* The checkpoint on the far right primarily serves the G concourse. From memory, this checkpoint has two x-ray machines.

You can access all concourses (and even other terminals) from any security checkpoint.

I personally avoid the main checkpoint at all costs. Under normal circumstances, I head to the far right checkpoint, where lines rarely exceed 5 minutes. If I see more than a dozen people in line (I'm impatient), I'll head to the elite checkpoint between the L and K/H concourses. I find that it's rare to wait more than a couple minutes at this checkpoint.

I haven't flown AA for more than a month. Can anyone update with the location of AIT/NoS machines? Can anyone update with the number of x-rays at each checkpoint? What about the checkpoints at other terminals?
