Airfare to Orlando in December

[Disneykarem]

What is a good fare for an early December trip from Atlanta to Orlando? I haven't flown in years so I really have no idea. Airtran and Delta both have flights for $138 round trip which seems good to me but I'm just not sure. Should I book now or wait? HELP!

Thanks for any help you can give!

Looks like a good deal for $69 one way or $138 rt inc taxes. Southwset has flights as well. Flying into Tampa with Delta or AirTran $118 rt inc taxes as well.
