I really love that we still call these airport-adjacent parking lots "cell phone waiting lots." At…read morethe time (after September 11, 2001), it made total sense. These were free parking lots where you could wait for people you were picking up from the airport. They called or texted you on their cellphones when they landed, and you responded with your cellphone.
Before the ubiquity of wireless phones (not to be confused with cordless phones), picking someone up from the airport required you either to park and go to the terminal to wait for them or to try to time your arrival so that you could pick them up without getting hassled by the airport police or local police or airport security or Homeland Security to move your car.
Nine-eleven meant non-passengers could no longer go past security, and the general fear of terrorism and/or bombings meant local authorities didn't like cars or trucks sitting next to airports, so the big airports (LAX, O'Hare, ATL, SFO, JFK, Logan, etc.) built parking lots that were free, but more importantly, they were far from the target-rich airports themselves. (It used to bother me just how far these things were from the terminals until I realized that the distance was one of the major concerns.)
So they should be called "pick-up waiting lots" or just "waiting lots" at this point, but we did used to say and write "cell phone" all the time, even long after it was clear we were no longer referring to landlines.
I only lived in Southern California briefly after September 11, and when I did, I normally built time into picking people up from LAX, so I never really used or knew where the Cell Phone Waiting Lot was. But in the last three years, I've been here at least twice, once to pick up my brother, and I believe the other time to pick up my nephew.
It's way too small for the size of the airport. Way too small. I always tend to think O'Hare's and SFO's lots are too big, but I'd rather have too many spots than not enough, and this one borders on not having enough. It doesn't help that they store lights, huge road signs, and other construction equipment right in the parking lot, taking away even more space. They do have porta-potties, which I guess is great in an emergency, and the handwashing stations are outside, so they're less likely to be gross.
The location is also pretty bad. It's hard to get to, difficult to navigate once you get out of of it, and not very convenient for most of the terminals past the Bradley Terminal as you go counterclockwise around the airport.
