I know people who do it all the time without dry ice. Look for a quicker flight. You should find something with lay over about 24 hours. LAX used to run Thai airways direct to bkk but that was a long time ago and not available. 18 hours. You can find good beef that’s imported now. But pricey. I wouldn’t try it.
I’m from the USA also, maybe bbq stuff or higher end kitchen stuff and utensils and such. I finally found a great bbq grill after joining Lazada on line app same as Amazon. I’ve been coming to Thailand 24 years and things are much better now than many years ago. Seems like I can find everything I need now at big C or lotus stores. I still can’t find big sticks of speed sticks deodorant though 555
