There are a few that are still hiring but it does not look that this situation will last long. Last i heared, Comair is still hiring as well as ASA. I may be wrong though. Check this list:
Airline pilot jobs-USA list and start checking each one of the links to see if they are still hiring.
You didn't mention your experience but if you are a CFI with only flight instruction experience, as your username suggest, it may be impossible nowadays to find a job. There are many experienced airline pilots in the market looking for a job, and soon there will be more. It is unfortunate, but these are bad days for the airline industry.
