Otherwise you have to recheck your bags in Bangkok.
About the bags, I did call BKK and they said we could "check through" our bags but we'd have to call Emirates (the airline we are taking from the US) first. I tried calling them and they didn't seem like they could do it, but the lady on the phone seemed to have a hard time understanding what I was even asking for...
Thanks for all your help everyone!!
