I filled it out too. Aside from its UK orientation, there are a few other problems:

1. There is no such thing as an alliance (oneWorld, etc.) frequent flyer program. There are frequent flyer programs of airlines that are alliance members. Not the same thing

2. "Do you have lounge access? Yes/no" is too simple. I have lounge access when traveling outside the U.S. on airlines that are members of oneWorld or SkyTeam, but not otherwise.

3. In question 17, it is possible for someone to have fewer than three preferred airlines - but the form won't proceed unless you fill in three.
