HYou have no clue about what I know and don’t know — this is for sure.
The filed economy class fares for September CPH-US-CPH travel for the TATL-flying industry cartel kingpins was lower than any round trip fare I have ever seen DY sell for September CPH-US-CPH for example.
Sub-$290 all-in ticket prices, with it as low as under €155 round trip on some legacy majors.

Who is trying to run DY into the ground? Certainly not DY itself, as good a job as they do of it themselves. The predatory pricing is being done by legacy majors, no less so when the variable costs of the legacy majors tend to be higher than the variable costs of an LCC.
