Another nice Aeromexico sale this time from Toronto and Montreal with prices in the $1440s range. I selected Labor Day weekend (even if it's a US holiday as YUL and YYZ can work for US based flyers) Some flights to GRU are on the 787-8 with 2-2-2 seating and some are on the 787-9.

Toronto: 19884 MQMs, 26512 RDMs, 5302 MQDs - FlyingBlue XPs (108 YYZ-MEX 24*2 + MEX-GRU 30*2)
Montreal: 20754 MQMs, 27672 RDMs, 5534 MQDs - FlyingBlue XPs (108 YUL-MEX 24*2 + MEX-GRU 30*2)
Usual warning with crediting Aeromexico to Delta... keep all Boarding Passes, request that your SkyMiles number be added at Checkin and keep screenshots of the purchase email and other communications indicating that it is a Business Class fare...
