First Class Flyer exists to instill and to continually hone The Upgrade Mindset (TUM).
You might be someone who would otherwise endure economy because First Class and Business Class is far too extravagant.
Or someone who would never endure economy but loathes, nearly as much, paying outrageously for First Class or Business.
The Upgrade Mindset is handy in either case.
It turns endure to enjoy.
NB: achieving The Upgrade Mindset can take some diligence.
But it does get you up front.
Diligence beats extravagance.
