Quick piggy back to the question of Tickets, I spoke with the NDR people in washington because the NDR report I got I thought had a mistake, but anyway, they told me that the report that the airlines get on a person only goes back 5 years, yet a lot of apps I have seen ask for tickets going back 10 years.
My point is that I wouldn't worry about tickets past 5 years since the airlines appear to not have access to that info.
