Perhaps checking on the TSA website or airlines website would be best.
... I suppose no passport, correct?.
We find those easiet when traveling.
( as an aside several states will eventually Require Passports when flying, as their licenses did not meet federal guidelines... one can google that for dates/details)
I'm of the mind, better safe than sorry... so just bring it, and If needed ..no issue for ur family.
Safe travels and Enjoy your visit!
