After filling out MANY surveys for e-Rewards I have to say this was more attractive and user-friendly than most. Two comments, though: first, you ask how often people "travel"- you may want to be more specific and ask how many round trips they take by plane. I do several road trips a year to visit family and didn't count those, but you may get inconsistent responses.

Second- you'd asked about preferences for various aircraft configurations (2-3-2, 2-4-2, etc.). Why would anyone choose the more crowded configuration? I'm not sure you'll learn much from those answers except the obvious: we don't want to be crowded! The only exception might be people traveling with children who want 3 seats together.
