IAD A gates ....hum.. no inbetween there... you either get great service.. or it sucks..... mostly sucked.... much preferred parking over in the C concourse at IAD.
When I flew for S5 we did Kingston Jamaica turns out of ATL.... like a freaking bee hive down there.... plus you could usually get a ramper to go get these empanada like sandwhichs for like 2 bucks a piece.... bottom line the service we got down there was every good or better than the DCI service we got in ATL.
