Asking for my daughter... She's luckier than me 😢

[Megandllsmum]

Two weeks today daughter and her boyfriend are off to Vegas, LA and then New York she's having a few last minute wobbles so rather than her stress out and in turn stress me out I said I'd ask you guys lol.
When she's doing her internal flights one to LA one to NY cos she's a fussy eater and has snacks she won't have to declare them will she as they arnt brought in from out of US, plus I told her she won't go through immigration on those flights as they are internal... Hope I'm right or I'll be in bad books giving her wrong advice 😐, she is all organised but just sweating about the finer details now, thanks and I'm sure I'll be asking more next few days x
