Even if it did, the amount of "lobby time" would still be drastically lessened just based on frequency of departures and decoupling of passengers and elimination (presumably) of the checked baggage situation.
TSA security checkpoints suck, but IME they "only" represent about 15 or so minutes of the extra time required for airport lobby time (on average; sometimes more sometimes less. Which is at least 14 minutes too many, but hardly the whole 1-4 hour overhead often cited).
Most of the overhead of plane travel in terms of airport and tarmac waiting time is due to deadlocking problems that occur in coordinating all the passengers into a single vehicle that is as full as possible (to maximize the airline's profit per trip), so you get a very uneven/lumpy demand curve based on when flights are scheduled, all sorts of complexity due to the system of having to check bags into a separate physical compartment, etc. A continually operating system where you could just show up whenever, your bags stay with you for the ride, etc could easily smooth that out. Solve the deadlocking issue (and most of the hyperloop guesses I've seen do) and even if the security checkpoint stuff stays mostly the same you'll still have a far more efficient embark/disembark system.
True. In Europe we don't have TSA and yet one still would be wise to arrive at least an hour before departure (if one has checked baggage; half an hour otherwise) to an airport which is usually located 30+ minutes from the center of the city.
Times always add up like this - 0.5h to get to the airport, 1.5h on the airport, X h of flight and then up to 0.5h to leave the airport and another 0.5h to get to the city.
