Delta upgrade fees:
0 to 500 miles $50
501 to 1,000 miles $75
1,001 to 1,500 miles $100
1,501 miles and up $150
To Hawaii from Atlanta or Cincinnati $250
To Hawaii from Los Angeles or Salt Lake City $200
These are only offered when there are more F seats available than Medallions waiting to clear the upgrade list (thus, a general member on a flight where there are 30 Medallion waiting for an upgrade will not be offered the opportunity), and the customer must be on a Y/B/M/H/Q/K fare - L/U/T fares are not eligible.
