Wouldn't get too shook up over the class "cancellation". The 23rd was intended to be a CRJ class. They shifted the CRJ dates some with the award but the class is still taking place with pilots that were already on property.
Magnus, it would be a safe assumption that management is waiting to set any other class dates until SLI is sorted out to avoid the costs associated with multiple training/reinstatement events. Don't hold your breath waiting to hear anything before then. You'll just have to wait things out with the rest of us... The sky isn't falling, yet.
