I earned a total of 8,375 Membership Rewards points for the purchase, worth about $160, according to TPG's current valuations. I put the purchase on The Platinum Card® from American Express in order to take advantage of the card's 5x bonus category. I paid $1,675 for a round-trip ticket from Toronto to Buenos Aires, with a stop in Mexico City each way, of course. This trip came about because of a great fare (for business class) that popped up for a few hours several months ago. Not only did I get to earn a significant chunk of the miles that were required for my quest to requalify for Diamond Medallion status (spoiler alert: I made it!), but I also got to spend a weekend in one of my favorite cities on Earth. This year, I found another good deal for round-trip tickets between Toronto (YYZ) and Buenos Aires, Argentina (EZE). Last year, thanks to an amazing deal, I got to fly the carrier's 787-8 on a long flight between its hub in Mexico City (MEX) and Santiago, Chile (SCL). Among the new aircraft it has bought, Aeromexico has taken delivery of 19 Boeing 787 Dreamliners - nine of the smaller -8 variety and 10 of the longer -9. Mexico's largest carrier has modernized its fleet and tweaked its route network.
