I've been lucky enough to fly business class with work - Virgin from Heathrow to New York. A car collects you at your house and drives you to the airport. You are checked on to your flight whilst still in the car when you arrive, and your suitcases are taken out of the boot of the car. You then walk through security and passport control and into the lounge. I don't recall any queuing at all. I'm not saying the aggravations you discuss don't exist, but at the price point for SST planes (which I imagine would be predominantly business class tickets), they are dramatically reduced.
