I need a cheap flight from Detroit to Las Vegas

I need a cheap flight from Detroit to Las Vegas?
I need to get to Vegas over the Thanksgiving holiday and am finding the prices unbelievable. Does anybody know the cheapest airlines to fly during this or any other time? I have used Kayak and Expedia, etc. but most of them don't list the smaller carriers I may be able to fly less expensively.

Not sure what small carriers you are talking about. If it lands at McCarran Airport then it is either listed on those sites or on Southwest.com. Allegiant Air would be the smallest airline that flies from Detroit to Las Vegas but they will be listed on those sites. The problem you are having is the week you are traveling is the most expensive week of the entire year. What you see is as cheap as it is going to get, the prices will keep rising the longer you wait.
