The master thread touched on this, but I wanted to make sure I have it right.

We are flying Continental from RIC to HNL (layover in IAH) in a few weeks. After a 60 minute layover in HNL we're using United miles on Aloha (eticket) to go to Kauai. To return, the only change is we'll be leaving from Maui to HNL (again on Aloha), and after a layover going to IAH/RIC.

My question is, what is the best way to check bags for this? I would assume that if I obtain the proper info, I could check them in RIC and not have to deal with them again until Kauai (and RIC on the way back). I've seen a PNR # mentioned... I have paper tickets for the Kauai/Maui flight and they show a PNR #, but my etickets do not. Any help would be appreciated!!
