I just read through this whole thread. I have lots of fond memories from Mirabel airport. When my grandparents would come over from Austria, we would wait on the mezzanine and watch for them coming out of the PTV's and then get in line for Customs. It was so thrilling to finally lay eyes on them, start waving frantically to attract their attention, then see the look on their faces when they finally saw us!
The passenger terminal was so neat with all the glass, and the grey marble floors. Such a simple design with stunning results. I also always enjoyed the spiral ramps for the multi-level parking garage, even though I was far too young to drive. Never did get to drive on them myself.
I have some pics somewhere from a few years ago when I went up to Mirabel airport to witness what I think was the last public passenger flight to land there. There were maybe a couple hundred people in the far eastern end of the terminal on the mezzanine watching the planes come in from the east. I can't find the pics on this PC but if I do, I'll try to post them here.
Dorval just doesn't have the charm that Mirabel had for me, but that may just be nostalgia. I'm not a fan of all the walking at Dorval, then being funneled into a huge lineup for Customs. I've also heard that Dorval is one of the few airports where connecting passengers are required to collect their luggage and then check it in again at their next flight.
Someone here mentioned a fully built train terminal at Mirabel? I never heard that before, I wonder if it's true? If it is, someone must have or be able to get pics of it! I would love to see that.
