You just need to spend another $4,000 on the card to get a free round trip anywhere in in the US/Canada. Or get the free short haul flight with the 15,000 miles.
Not worth the $120 annual fee once you use up the points.
More to take in, every time you take off
If you're going to go with an Amex, the American Express Gold Rewards Card gives a bit more of a reward than the Amex AeroplanPlus card and the Amex rewards points can be converted to Aeroplan miles 1:1 anyway.
The Sept/Oct issue of MoneySense gives a good breakdown of the best rewards card in various categories, including the breakeven point on how much you need to spend each month to make the annual fee worth it. Try to only go with a card that rebates your first year fee, those offers aren't hard to find.
Also, for anyone choosing an Amex card, I recommend getting a PC Mastercard as backup because Amex is not accepted at a fair number of places.
