Sorry for not being clear... They use a corporate travel booking service but I use my own credit cards and can add all my frequent traveler numbers.

In regards to the Amex gold vs the TD aeroplan I assumed using the aero card to book AC flights would net me bonuses. I will look into it more but if Amex is the better option I'll switch out the card.

The first trip I booked with my boss and he's a Hilton guy so we're staying at the Hampton inn but future trips I'll stay at the Marriott as my wife and I booked Atlantis for December and were short some MArriott pts.
