Tkx all.
As I mentioned on another similar thread we have no expectation of nanny being able to walk up and down cabins. More like ability to relieve the pressures a couple of times during the flights. If the situation does not allow for a visit during the 12 hr sectors for any reason we have absolutely no issue heading the other way.
I note from one of your previous posts (albeit back in 2005) that you certainly don't want people traipsing through the cabin so am surprised you'd even ask about your nanny coming to visit you
Improve Raid the Larder- what a joke that is! (dont make food on demand as that will increase foot traffic and noise throughout the flight)
And although I appreciate it's not so easy with twins, as the majority have suggested you are making things more difficult for yourselves by taking non adjacent seats on the UD. Let's face it 4 month old infants won't know the difference between a bassinet upstairs, downstairs in CW, WT or Ryanair
(Just a thought, if you're both gold and travel 150-200 legs a year, could you not use miles to put your nanny in the same cabin as you??)
