ElI5: Why do we still have to check in for flights?

409 viewsEngineeringOther

And why (at least with my experience) is it normally only allowed 24 hours in advance? Why not more, less, or even not at all with modern tech able to know where we are?

I don’t understand “still.” Checking in serves the same purpose it always has – it tells the airplane that you will be boarding the flight, and how many bags you’ll be bringing. A surprising number of passengers pull a no-show, which allows the airline to offer their seat to a standby passenger.

Please explain how you think “modern tech” would eliminate this. I don’t want American Airlines tracking my location so they know if I’m in the airport or not
