Hi Kayla, and welcome to the forum!
The Swiss Transfer Ticket indeed allows for a free trip all the way from Basel Airport to Interlaken and back to any airport or border station, as explained by Jayjay. Details can be found here. You can order it through www.swissrailways.co.u k and have it e-mailed as an e-ticket.
By the way, a Swiss Transfer Ticket is very convenient, but if you need an exact return trip Basel Airport-Interlaken other alternatives may be slightly cheaper. You could consider regular tickets or a Swiss Half Fare Card, but this depends on your further plans. Advice on how to pick the best pass can be found here.
Jayjay, thanks for your input!
