Appropriately, the lyric, "...you don"t know what you've got til it's gone..." is from Joni Mitchell's Big Yellow Taxi. At LAX, you once could exit the airport board a taxi, shuttle, UBER or LYFT and be on your way home.
Until construction is completed, sometime in 2023, you now board a shuttle to an offsite location called LAXit. From there you connect to your transportation home. This would be but a minor inconvenience, except that the airport missed the obvious. Passengers have luggage.
If you are returning from a long weekend with a smile and a carryon, you are probably OK. But on these full buses, there is little room to store full sized luggage. LAX must reconfigure the shuttles.
