When Delta changed its seat map this Fall, some of my requests for seat maps using Ben's site (http://www.benedelman.org/travel/dlseats/) would result in an error "not available".

I finally figured out my problem. The day of the month needs two digits. For Jan 2nd, I should have put in "02" verus "2".

As an aside, Thanks to Ben for a GREAT TOOL!
