In percentage of fare terms, for most routes in North America there is a big difference between Latitude and Executive if you book online.

Whether one thinks Executive in North America is worth paying anything above Tango Plus is of course a matter of opinion. Personally I would consider paying for Latitude for YYZ-YEG or longer as generally good value.

Executive First fares to SYD ex Canada are usually about 2.5 times that of Latitude Plus fares. YYZ-SYD-YYZ for 4200 in the big seat is pretty good. If you have 4200 to spend anyway.
