We always just sit in the first place that looks agreeable..Not the very front row though as we always have something to put under the seat in front of us, which the front row doesn't have. (unless you're on a plane where the front row is backwards and faces the 2nd row.) We like close to the front because the plane unloads from front to back. If the flight is going to full we just grab the first 2 seats that are next to each other.
