I'd agree that the e-mails go out exactly 10 days prior, as I got an invite for flights on the 22nd. Looks like some of the errors might be cleaned up, as there were no typos in mine, and links functioned properly.
The bid range was $350 to $800 for YYC-YYZ and $95 to $200 for YYZ-YOW, both on the 763. Hard pass on either offer, given there's likely minimal chance that many will bid at those prices, and from prior Xmas experience, there's at least a 30% chance of an op-up as a 50K. Otherwise, bulkhead pair for such short flights is fine with me.
