You’re booking a flight online, and you’re at the final step of seat selection: unless you commute on a plane, you don’t know which seats are the good ones, beyond your normal aisle-vs.-window preference.

SeatGuru provides schematics and advice on seat selection for airlines and their fleets of planes (your airplane model is usually known when you book your flight). For example: “rows B, C, and H have restricted seat leg and storage room due to an underseat equipment box”.

Sweet.
