My daughter is flying in (to Japan) for a holiday visit next month. She'll be flying out of the the U.S. from LA, then she changes planes in Seoul before flying here to Miyazaki.


She's 19, can she legally buy alcohol at the duty free shop at LAX?
How about Seoul, Incheon International?

If so, do you have any suggestions (bourbon, scotch, or irish) on what I should ask her to pick me up at either of those two duty free shops?

I appreciate any help you can offer.
