If you mean the "Contract of Carriage" there was something on a US news magazine show last summer about having problems getting a copy of some major US airlines "Contract of Carriage". Just for fun, I e-mailed Northwest, with whom I fly the most, and I had one in hand within 3 days. Just for laughs, I may try some other airlines, too.

Also, legally (in the US) an airline is supposed to be able to provide you with a copy when you check in. Not that in actuality that is the case....
