Frontier Airlines EarlyReturns - Seat Selection Online?

Does Frontier allow you to choose/change seats online? I can't seem to find this option anywhere.

Thanks!

You can select your seats online, but it comes late in the process (possibly only after purchase). I don't think you can change seats on-line but I have never tried it. How's that for a not-very-helpful response?

Yes you can choose your seats online, but if I remember correctly there was some type of drop down menu that asked if you wanted to choose your own seats or if you wanted an isle or window seat. I picked the choose your own seat option and after I bought my ticket it took to a seat selector layout.
