Has Anyone Had Success in "Persuading" DL to open up "Z" Inventory
I have purchased a "M" fare from Columbus to Sydney via Los Angeles. Both DL.com and EF show tons of J seats available for purchase but with Z0.
In fact, many other flights have far less J inventory available for sale but show Z>0.
Has anyone ever called the Diamond line and successfully gotten a J seat flipped into Z to allow usage of those lovely SWUs?
