i was in prestige and my sister was in first. i asked the flight attendant if i can go see whether my sister is awake or not. i was told yes but make it brief. the flight attendant told me how to get to first (which stairs to take and etc) and i was allowed to go on my own. but my sis was asleep so i only stayed a minute to leave her a note. after that, like five or six flight attendants checked on my sister every 30 minutes to see if she was awake and updated me on the 'status' of my sister. my sis slept the whole flight (pretty much) so i had flight attendants coming to me every 30 minutes for like 10 hours. it was an interesting flight.
