Does anyone know the best way to get a decent deal on a last minute flight? I just found out my sister is pretty sick (think autoimmune disease attacking her liver, not the flu...) and going in for a bunch of tests. I'd like to be able to fly out (from San Diego to Pittsburgh) to help take care of her daughters and household and everything. The cheapest flights I can find leaving in the next day or two are $600.
Any suggestions?
