Moderator note: This seems to primarily be commentary about Prince of Travel rather than AC, and unless this thread becomes a lot more relevant to AC very soon, I expect this thread to be moved to the FT forum dedicated to talking about things like travel blogs:
External Miles and Points Resources
Putting my moderator cloak aside for the moment, I'll note that the Altitude branding died after AC bought back Aeroplan, and hasn't been used in about 5 years.
