As has been pointed out, air travel generally is still much cheaper than it was 15-20 years ago, even more so when you factor in inflation. Also, start doing some analysis on other modes of transportation and the associated costs, and you'll likely be surprised.
And what is the 'yay' for if it forces people who are bad at math into their cars? I'll guess it is one of those environmental 'airplanes are bad' ideas? Have you done some specific fuel consumption calculations for driving vs flying? I ran some numbers a while back, and I am too lazy to do it again, but realistically you have to have 3 or more people in a civic between YYC and YVR to have a smaller 'carbon footprint' than getting on a 737 NG with 130 people on it.
But what do facts and certain environmental special interest groups have to do with each other.
PS. But yes, book before midnight tonight to save yourself the fuel surcharges at westjet.com
