Absolutely, I'm almost certain it could be as efficient as a train as most of the security is pointless theater. When I was flying more often I would leave much less time and usually not miss my flight. Sure, something could go wrong and I would miss it but the hours saved not sitting at the airport outweighed a potential occasional missed flight and the extra time that would take to re-book and come back.
