Cyrano, thanks for the corrections about the CRJ-700 chronology, I should have checked instead of working from memory. Interestingly several of these have never found new homes and, more than three years on, are still stored belonging to Maersk's finance offshoot. So maybe they would have been better to have let Duo's business roll on.
But then, if Maersk corporate (no fools in the business world) decide not to put any more money into it, and then subsequently an independent investor decided not to put any more money into it, maybe that tells us something. I am sure that service style, etc, was done all very nicely, but if the investors cannot make any money, what's the point ?
High load factors maybe, but at what fares/yields ? Also you often find that "high loads" can be a partial view, it's only on a limited amount of the total network, or it's certain departures only (eg "they're always full on Friday night"). You need the complete picture.
