I have a complex routing coming up and am not sure how the luggage checking process will work. Trip is as follows:

MSY-DEN UA
DEN-SFO UA
SFO-HKG SQ
HKG-BKK TG
BKK-HKT TG

All issued on a single e-ticket. Is it just a matter of checking in at MSY and then the rest will be taken care of? Or will I need to re-check the bags at some point along the way?
