If Delta were to retain everything about Worldperks today, except for eliminating EUA and the complimentary upgrades to First Class, while at the same time essentially putting out a real FC product with real FC service, hot meals, the works, at high but doable prices and which is only available for purchase or the odd op-up exceptions, would you stay with WorldSkyperks?

How important are the FC upgrades for elites?
Are they the main or only reason for many to choose NW and later Delta?
