Going to Thailand and have a 12 hour lay over in Seoul. I have a "Scotty" jacket thanks to Scott Jordan (it has a LOT of pockets) so I am carrying my meds, contacts, passport, credit cards, toothbrush,cell phone and charger and more. So my carry on is small but I do have that long lay over in Seoul. So do I check my 1 bag or do I carry it on?
