Need help clarifying about starting classes

[Anova]

Also, be aware that you only get airship transport starting after a lvl 15 story quest. If the next class you're interested in is in another city, you might have to spend some time walking to whatever city that has your class or buying the lvl1 weapon from the auction houses (which will be much more expensive than they're actually worth).

I don't expect it to be a major problem, but it's something to consider if you're prioritizing a role.
