This piqued my interest as I have a lot of travel booked in and out of Tasmania.
Called my friend in QF and yes you are right they are reshuffling equipment around the network to respond to the demand going up.
Lonny is being upgauged from Q400 operations to all 717 operations - about a 10% increase in total seat capacity from pre-covid schedules early new year. So they will be running 717 ops from both MEL and SYD into LST now. Probably also picking up slack from Virgin 2 who has really scaled back their Tassie flying very dramatically.
I checked my forward bookings and pleasingly the night time flight out of MEL has returned and the early AM flight out of LST is back on, they are overnighting a 717 in Lonny to do this. I called QF and got myself moved around at no charge as well
So good news for Tassie and for business flyers as some business friendly slots have reappeared.
Wonder where the Q400s are being redeployed.
