by the way at DFW the train is called "Skylink", not "skytrain". if you see signage for Skytrain that means you've somehow ended up in Vancouver, Bangkok, or somewhere besides DFW airport.

you must go up one level to board Skylink (all airside). there are escalators leading up to (and down from) each station in two directions.

the B & D terminals are on one side of the airport complex, A/C/E on the other. the trains will thus go A-C-E-D-B-A or A-B-D-E-C-A. signage at each station will help you determine which train will get you to your destination quickest.

Hope this helps. enjoy Hawaii.
