checking bag during stopover
I couldn't find a baggage thread or an answer to this question anywhere, if I missed it mods feel free to move this.
I have a bit of an odd situation regarding baggage. On an upcoming flight I'm routing LGA - DCA - BTV on US Air with a 3.5 hour layover in DCA. I'm going to BTV for vacation so I need to check a bag but I'd prefer not to bring it with me up to NYC during the work week. However I live pretty close to DCA and would have more than enough time to get to and from DCA to get my checked bag during a 3.5 hour layover. My question is whether I can then check my bag when I get back to DCA for the DCA - BTV portion only since I'd be checking in a mid-trip (fee is not an issue as I'm *G so I'm not worried about how / what they would charge me since it will be waived).
