Canadian Airport Thread II

[IRT_BMT_IND]

I said this on UT, but the proposed YYZ expansion (assuming the renderings reflect the actual plans) seems pretty well laid out and will address two big operational problems with T1, by having international domestic swing gates and putting the preclearance area on its own floor (like the Z pier at FRA), rather than using linear separation and using movable walls and doors (this also means the different parts of the airport will feel less walled off from each other). So flights bound for both the US and other parts of the world can load at the same time from adjacent gates, with precleared passengers kept separated on a dedicated floor. Or a 777 can arrive from YVR, deplane passengers into the domestic area, and then load international passengers to HND without having to tow the plane across the terminal.

The downside to this kind of design will be lots of walking for connecting passenger (if the GTAA is smart they will build walkways under the apron between the piers) and the internal layout of the terminal will likely be diabolically complex (if you've been through FRA you'll get what I mean).
