The airlines commonly (universally) cram a first and middle name together with no space, and this never seems to matter. I know there's a certain degree to which the info that goes to TSA about who you are isn't exactly a match for what's in the airline's reservation system and what's on your boarding pass... to what extent it's that system at work here vs. the name actually not mattering that much isn't really clear to me.
