See my post above. The "no changes" statement is actually a bit of a fib meant as further discouragement from buying these. Since you can cancel for full ecredit apparently, you can still effectively make changes to a Basic fare for the fare difference. DL makes same fib in their BE marketing, but has a $99 fee. The DL BE fare rules actually directly contradicts their marketing language of BE fares being "non-changeable".
