It's actually getting better. Really. I live South of the Airport, and we had been flying exclusively out of TF Green in RI for a few years because Logan was such a nightmare. Past 3 years, we've gone out of Logan and it's not been bad. Of course, rush hour is always an adventure, but other than that, follow the signs, get good directions, and you should be good to go.
Getting North out of the airport is easier than going south, so that works in your favour as well.
Good Luck!! and have fun when you're here.
