First class service
As a "VIP" passenger in the first class, even if he arrives at the airport 41 minutes before departure, he can quickly pass the security check and register.
First-class passengers also enjoy separate direct passages, and some even have direct safety passages. On the same flight, planes take off and land at the same time, which saves a lot of time from boarding to disembarking. Of course, first-class passengers have more than these advantages.
The most important thing is the cabin environment of "VIP". A first-class box like the empty A381 is six economy class sizes, which is more than average.
