What is the cheapest and most efficient way to travel from DFW Airport to Austin Texas?

I would like a cheap alternative to a roundtrip flight costing $150 to get from the airport to Austin. I have been searching for bus companies but this seems not to be working out. Any suggestions?

Why don't you drive? it is not that far if you start driving in the early morning before rush hours (7-9 am) and you will enjoy the view and have a car when you are in Austin.

rental car. austin is only a few hours (3) south, straight down I35 from dfw

did you check Southwest Airlines? They've been advertising $49 each way ...

I would rent a car. Just aviod arriving Austin during rush hour traffic. The major bleed into Austin (I-35) is a nightmare. Also watch your speed in the small towns before Austin (ie..Georgetown). The traffic cops in this area are real bad.

ps... right before you hit Austin limits there is a new Outlet Center that is worth checking out and an IKEA.

Rent a car, or drive your own. It's about 4 hours from Dallas to Austin (traffic jams notwithstanding) and you can get some good rates from car companies in the area - including those at DFW airport.

You could ride amtrac for $31. I would opt for flying out of Love Field Dallas on Southwest or renting a car myself.

You know, you might just want to take the flight. Driving to Austin will take you about 3 hours from the airport, whereas if you just took a connecting flight you'd be there in the same amount of time, and not have to sit in the horrible Austin traffic on I-35.

It's either that or a rental car, which could cost you as much as boarding another plane (with the gas and all).
