The Disney Parks Blog has revealed that the refurbished Star Tours ride's flight list will be coming very soon. No other information has been released at this time, although interestingly, the blog post does include a destination chart written in Aurebesh. Check that out below (click to enlarge).
If you have your translation guide handy, you can work out the "Basic" version of the chart, but don't get too excited about visiting all those locations in real life. The blog post notes that "while the Star Tours Company does fly to many destinations (as you can see in the attached image – especially if you read Aurebesh) we’ll soon give you the flight list for our show!" Ergo, this chart probably refers to the available destinations for the in-universe touring company and not its Earthly counterpart at Disneyland and Disney's Hollywood Studios. Time will tell!
