Isn't the DH3s fleet slated for a full cabin refurbishment and life extension program in partnership with Bombardier?
After about 500 miles, the DH4 becomes slower. But the DH4 can operate with low load factor and still be profitable. The DH3 refurb is done, and BBD no longer owns the type certificates or maintenance for Dash-8s, that's now over to Viking.
