Fairly pessimistic outlook criticalmass...
With Wollongong being Australias 10th largest city and 80km from KSA or well over a 1 hour 15 minute drive, it has amazed me that the likes of REX have not jumped at Albion Park
Gold Coast and Sunshine Coast are both 100k from Brisbane and just 1 hour away and although they are touristy destinations, each support huge passenger numbers
Even Wellcamp is supporting multi-daily flights to Melbourne and Sydney
I think Jetgo will have great success on both routes with exactly the right sized aircraft for the routes and will likely end up 2-3 times daily on each route
Here's why
1) Those getting international connections will likely save money, even with the JetGo fare as there is greater discounting at Brisbane and Melbourne than Sydney
2) Those traveling from the Gong to Brisbane or Melbourne have a greater chance of making it to the airport on time at Albion Park
3) Albion park avoids the F6 M1 and often hours of fun and games and fog etc
JetGo just needs to keep in mind 2 things
1) keep flights on time
2) keep fares reasonable
The rest will take care of itself
