Is inviting a guest from economy or business into First class normal?
I recently took a flight in LH First Class and I saw that a guest normally seated in Bus or econ took place at the ottoman seat of a guest seated in First class.
Btw, first class was full so there was no seat available.
The crew served both first class meals.
Is this common?
If yes, what if each first class guest invites another guest to have a first class dinner together.
The guest even got a first class pyjama.
What do you think?
Is this still first class?
