If you’ve ever trudged down a jet bridge and thought “surely there’s a better way”, you’re not wrong — and for a while, the aviation industry genuinely tried to make boarding planes work very differently. In this video I look at the alternate timeline where airports leaned into big, ambitious systems: mobile lounges that carry a whole cabin of passengers to the aircraft, passenger transfer vehicles, and even concepts like Plane-Mates — essentially turning the bit between terminal and plane into its own moving room. But the key takeaway is that “cool” isn’t the same as “practical”. These systems promised faster turnarounds, less walking, and more flexibility about where aircraft could park — yet they come with their own costs: complexity, staffing, maintenance, and the awkward reality that every extra vehicle is another thing that can break, queue, or get in the way. I’m at YUL Montréal–Trudeau International Airport to ground all of this in the real world: how airports actually move people today, why jet bridges won, and why the future of boarding is usually less sci‑fi than the concept art suggested.
