Unfortunately, I don't see people lugging baggage and/or children or other loved ones taking transit to the airport.

Nor do I see the myriads of relatives meeting family/visitors from their homelands taking transit to the airport either.

Who does that leave?

The same people that make up the Union Express passengers - the airport workers.

And, unless Ontario and the GTA get their transit plans in order nor do I see people flocking to this hub as an intermediate point in their transit travels.

What I do see is more bureaucracy, high paid jobs, higher airport fees, years more of construction congestion at Pearson, bigger parking lots, etc.

Doesn't make much sense to me but then I just use Pearson as an airport.
