The 737 is a one off. It's under management and used by Sheik Al'somethingorother to fly his pet horses around Europe. Although our management would like to get their mitts on it to fly boxes around the Sheik would rather they did not.
The Electra is not being phased out in any systematic way. The planes are getting towards the end of their working life and some are probably not capable of passing C checks. Replacement was a big topic a year or two back but for now management seem more interested in the Gay TP (ATP) and winning new contracts for that. So, who knows what the future holds.
