Welcome to MySwissAlps!
I did a quick check for a random date and the first train arrives 12:23 PM. What's your travel date? A flight won't get you there earlier, unless it's an extremely early flight, which I could not find. I would just take the train. It's comfortable, eco-friendly, and pretty cheap (€ 50 or less) if you book your ticket early.
If you intend to buy a train pass for Switzerland, e.g. the Swiss Travel Pass, you only need a train ticket from Paris to Basel (the border). Please see myswissalps.com/ traintickets/ france.
Note that the town's name is Interlaken.
