Most of the destinations shown as examples in the article -- SYD, JNB, Hawaii -- have long had issues with decent premium cabin awards. Not trying to defend DL here, but there are definitely other markets where the deals are not so terrible or difficult to find. Here's the flexible dates calendar for roundtrip Delta One flights between 4/29 and 5/8 on SLC-LHR. Don't know where the guy was getting 400K miles. No these aren't all non-stop's, but then AA/UA do not have non-stop's this route so how is it valid to compare to DL non-stops??
