Yawn. I've said for 2 yrs now that AC is moving towards a E/E+ airline with emphasis on paid E+.
Your E/SE benefits mean little these days. Paid LMU and MLL access is offered even with base Tango fares these days.
AC as we know is a chronic money loser and must be desperate. Ripping a row of J seats out of the A320s was your first clue as to how greatly your status upgrades are valued.
Maintaining a costly and bloated 3 tier status system is just not worth it. Selling MLL access & food at $30+ a head however is worth it. The MBAs and yes-men are salivating over these "marginal revenue maximization opportunities". Cue the Powerpoints!
