We as the travelling public will need to adapt and accept the new reality of modern air travel and perhaps change our habits when arriving at an airport going forward. Events like 9-11 changed everybody's travelling habits for the worse but this move can change for the better. I believe one of the improvements in the IFP will help soften the urgency to get there as early as possible.
Some friends of mine will arrive at the airport 3-4hrs early, even for a domestic flight to Van or TO, it's insane.
Even with a boarding ticket already printed out and carry on bags only, they would be the prime fodders for all the retail vendors in the commons to grab some of their money on food and merch since they'll be so bored and probably hungry. Maybe YYCAA is secretly hoping steady streams of those types..
Over time, most people who are regular travelers will adapt to this and irregular travelers may simply follow the queues of what everybody else is doing once they are at an airport. That might be the main human communicator to get everybody else in sync with the new program as intended by its very design. Though people should get the opportunity to know & yes pay attention if something new is being implemented which will affect the way they transit in a modern 21st century airport.
That will be the airports job, the airlines, and even media outlets touting this to communicate this effectively so we can accept this and make the steady improvements we need to make to experience this in a positive manner.
I give kudos to yyc for taking some of the modern design systems that european airports currently use.
The world's busiest Int'l airport LHR already uses this system extensively and almost a hundred million travellers who transit through there (well QEll and T5 at least) breeze through this in a sinch, and they probably have even more irregular travellers sharing the same kind of gripes many Calgarians currently are. (But LHR also has water stations to quell the gripes

)
I always travel and whenever I show up to an airport (EU airports particularly for Europe travel), I am so well prepared that arriving 1hr prior to departure or even 45mins I can breeze thru security, grab a snack or my own drink at a vendor and then go to my gate as it will already be assigned by then. Many systems are in place where I am able to comfortably execute this kind of tight transit over there, I feel good that eventually the same sort of expediency can be possible at our airport too. (I show up 1.5hrs usually)
Otherwise great discussion, I am learning lots and there are lots of valid points of pros and current (hopefully short term) cons.
