I'm finding it's a pain in the ... to hunt for the lowest fares on TATL / TPAC flights.

I have time freedom. But I don't want to overpay.

Has the cow made an app to find best possible fare or do any of you have a better way for me to find great prices on AC?

Unlike many --- I've always liked flying with AC. I have great experience with service / Upgrades / etc so I am preferential to hunting down fares based on AC fare buckets.
