Just called our adult children to see if they wanted any of these 20% discount codes and we had an interesting discussion re their potential value.

With the discounts being restricted as usual to base fares but in this case further restricted to only Tango fares, savings potential are somewhat limited.

Has anyone figured out the most that can be saved, bearing in mind that only AC flights may be used? SYD-YYZ-LHR and NRT-YYZ-TLV are obvious, but since most of us live in Canada or the US the above routings are impractical although valid.

Personally I'd rather see a 10% off Executive Business or 15% off PE! I know; dream on!
