The Canada Line’s Vancouver stations–at least City Centre and Broadway–have machines to let people flying out of YVR check into their flights.  Even if it’s only useful for people carrying on, that’s a really nice touch.  There are three things to stress out about when you’re trying to make a flight: getting through traffic to get to the airport on time, getting through the lines to get checked in, and then getting through the lines for security.  The Canada Line and those machines make two of those things a lot less stressful.
