Flying back and forth across the country, I quickly learned which seats were the best ones to request. But there’s an easier way than trial and error.  SeatGuru.com.  It lists interactive seating maps for virtually every aircraft on every airline. It can’t keep the unruly children or heavily perfumed women from being seated next to you, but it is the quick and easy way to make sure you don’t get stuck in a seat that doesn’t recline or faces a lavatory.
