People don't seem to like to go there because it's too far away from the city. However, personally I find this is a bit ridiculous. It is about a 35-40 minute drive to Mirabel from the very heart of Montreal... that may be a little bit more than what people would like, BUT it takes a good 20 minutes to get from downtown to DORVAL, too! So basically, people are claiming that Mirabel is unattractive because it has this "distant outskirts" image, but really all we're talking about is a difference of FIFTEEN MINUTES. I think the distance issue is mostly in people's imaginations. On the 35 minute drive, you pass by some farms, so I guess it *feels* like you're going too far out of thie city, whereas on the way to Dorval, all you're looking at is CONGESTED highway. For a while, I believe all international (not counting US) flights had to be done out of Mirabel, so it was really growing, but a few years ago ADM and the government decided to allow int'l flights from Dorval again. I'm not sure what their aofficial reasoning was, but I guess it came down to the distance issue, because that's about the only major advantage Dorval does have. So now only vacation charters and cargo use mirabel. At Dorval they're building a new transborder finger (Felix Sieder has some pictures of it on here), but to do that, they're having to take down some hangars! There's just no room left. Also, Air Canada is sorta based at Dorval so maybe they don't want to move much, and they have a lot of power. Some people are saying that the new Canada 3000/Royal/CanJet should make Mirabel their hub. If they did, they'd hav ea world-class airport just about all to themselves. However, it's a big risk to bet that they can get business travellers to make that (ahem) *long commute*. Also, if Mega-C3 is based at Mirabel, travellers won't be able to use their flights to connect to others, if the other airlines are still at Dorval. ADM and the government seem to be staying focused on Dorval at the moment, especially with the new construction there. But if the economy stays (gets?) strong here, Dorval is getting pretty darn close to it's capacity, so Mirabel's day may yet come.
p.s. One interesting fact that many of you may not know about Mirabel is that in terms of actual geographical area (certainly not in terms of paz or a/c movements!), YMX is actually the largest airport in the WORLD. SO, there's plleeenty of room for it to expand, unlike Dorval.
Next flight.... who knows.
