Agreed, no real need for airport extension if the UPX is driving to that 7.5 min frequency and stopping at Woodbine. Now, if Dixon ever warranted extra service, maybe a BRT from Scarlett Line 5 station up Scarlett and across Dixon to the airport (wide ROW, lots of density between Islington west to 401), then maybe I could back an extension to terminate at Dixon/27 to interchange with a BRT (maybe terminate in the land used for the NE Dixon/27 ramps adjacent to the Congress Centre) . But I'm not sure we're there any time soon.
