>airports are major passenger generators.It's still fraction of traffic, and not all people heading to the airport will have more luggage than a simple backpack. (I have flown with a single backpack on multiple occasions).
I used to wait at pic related very often in the evenings for a green line B train. I haven't been since renovations but when I was there, I'd wait right next to an escalator from the blue line coming from the airport. Every so often a flood of people come up the stairs and you know it's airport traffic because you always see roller bags. But even here, it's rarely more than 1 in 5 at most. Everywhere else on the map other than the Silver Line, luggage bags will be uncommon to downright rare.
