any ideas on cheap airline tickets????

to where? from where? when? how many? what restrictions are there?

From Ky to Colorado june 22-27 2 adults 1 9year old and a 1 year old.

Try Southwest.com. They have great deals if you book two weeks in advance, but it's worth a try.

Also try www.kayak.com, it compares airline costs.

Try Airtran and Jetblue as well.

You can also try usa3000.com, not sure if they fly where you need to go, but I think they are still offering $10.00 off each ticket with coupon code DAD, good luck

Try http://farecast.com. It tells you if it is a good buy or not.

Sidestep showed many options under $400/person round trip right now for those dates...I tried it as louisville to denver...you can try it with where you want to fly from/to.

Don't go through travelocity, had a horrible experience with them on flights being cancelled and them never notifying us. I heard though to go to your local airport's website late at night and check for deals.

www.priceline.com
www.orbitz.com

Also, try going right to the individual airline's web sites for airlines that fly out of your starting airport.
