Spiral Sitting
What the passengers sit up in the Boeing 747?
Since expanded the upper deck, first-class passengers do not sit up or coach or mixture of both? It is the spiral staircase leading up there, or straight? Sorry for such detailed issues …
The thought that varies from the line air carrier to most of Boeing 747 operators in first or business class passengers sit on the top floor. The upper deck is almost exclusively a class. The 747 older model, the 100s and 200s have spiral staircases, while the new-300 and 400 have straight stairs.
