For instance, American Airlines' app includes the aforementioned parking reminder plus it allows you to monitor upcoming flights, track your standby status as well as your frequent flier miles for elite status and much more.
There are similar functions on Delta's new app, Southwest's app and Alaska's app, too, and it wouldn't surprise me in the least if more airlines join in the app-craze before year's end. And this sort of technology is nothing to be nervous about -- hey, we all learned how to use email didn't we?
Of course, some of us are less technologically-inclined than others. Speaking of which, I asked my editor what her favorite app would be, assuming she ever breaks down and gets an iPhone; I braced myself for her response.
"I like that flashlight app," she said. "You know, the thingie that turns your phone into a light? Strikes me as very handy."
Well, at least she eventually found her missing car in that LAX parking garage.
