Go to ABF.com get the # for the location closest to you and call them to see if they are hiring.
As for the economy and the time of year yea this is a bad time to be looking for a job in general your location could be hiring they could be swamped with freight you wont know till you call. There is still freight out there to haul if you are in the right place i am not missing out on any trips here in the Midwest.
Is ABF a good company to work for YES.
You mention Yellow, I worked there they hire too many people they hire for peak biasness and lay off when it slows down. ABF is more careful not to hire to many that is not to say you wouldn't be lay ed off if you get on at a big break bulk but unless you are at a break bulk layoffs are the exception not the rule. If you can get on over here i wouldn't hesitate. There is a big background check don't lie on your app don't leave any blanks they will throw it right out.
My .02 cents good luck
