For the RTWs, though, the price seems to be the same everywhere:
140K / 220K / 300K for Y / J / F
DL offers the F award for 280,000 miles.

The agents I've spoken with insist it's not worth the extra miles for the F compared to the relatively inexpensive J at 220,000.
That's what we're doing, the J, in Nov/Dec.
