Which lounge in IAD
 

Hi all - I will be arriving into IAD in Y around 3pm from CLT and will then be departing to DOH on QR in J around 8pm. From what I can see QR use the Virgin Clubhouse, but seems to only be from 3 hours before the flight. On the OneWorld site I see there is also a BA lounge but it appears to be in a different area. Will I be able to use the BA lounge or will I be stuck only with the Virgin one from 3 hours out? I am OWS so should have the right to use the BA lounge. Any advice welcome.

All gates at IAD are in a single secure area, so you won't have to reclear security. I don't know if BA will admit you, but if they will, you should be fine.
BTW, I'm actually about to drive to IAD to pick up some friends flying in from CLT on US.
