Airlines also often hide seat availability on booking sites (including their own) for various reasons. expertflyer.com's paid account permits you to see actual seat availability. Especially when booking international flights for the family, I'll cross-check seat availability on expertflyer.com. If they show better seats available than the booking site, I'll book the flight and then immediately call the airline's customer service to request a change in seat assignment.
