In order to get a 4-berth coupe in FIRST Class, I have booked 4 tickets(myself, wife, daughter and 1 extra for 7 yr female kid), even though we are 3 persons. In that case whether, the 1 berth(extra booked) will be alloted to someone later by TTE? I have my friend travelling in FIRST class with his daughter of age 7yrs and can i show her as the 4th passenger? My friend has not booked a ticket for her showing her age <4 yrs.
