So true. Those of you getting class date changes, it reflects shifting priorities and a massive training requirement.

Recurrent Training
Upgrades to Capt. in both SAABs and CRJs
FO movement from SAABs to CRJs
Initital FO training in both aircraft.

Enter the changing ops requirements and demands on training. The need to have a specific number of aircraft types / crews available at designation locations to meet "about to be published" schedules DRIVES the training schedule. Small changes in the schedule can cause siginificant changes in the training requirements.

Next consider the limitations of simulators and instructor availability. Mesaba can dedicate its CRJ sim to Mesaba but Denver probably has other customers as does the factory simulator training center. If you look around, you will probably meet some very tired sim instructors.

Feel sorry for the training schedulers. Their shifting of your class date reflects the realities of the situation.
