I initially planned to do this flight in Business as the price difference between Y and J was minimal ($300+ vs $400+). However, price for Tango dropped significantly and I bought the tickets at $191 (excluding seat selection and baggage fee) while the price of Business Class remained at about $460. One month before travel, I tried my luck with a bid of $120 USD per person for upgrade but as expected the bid failed. I wasn’t too hard up for the upgrade especially after my experience on AC 307 (this flight was operated on Airbus A319). It has the exact hard product as the A320 (which wasn’t great).
