The Centurion lounges, like at SFO and DFW, are head and shoulders above other lounges, on a par with or even better than international lounges like LH and TK at IAD.(In fact, every non-UA lounge at IAD is miles better than any of the UA lounges.)And I wouldn't say the SFO UA lounges are pathetic – they are still better than a lot of the other UA domestic lounges.
