Perhaps not, but the best one going TATL to NY or D.C. I've gotten the escort from AF through security at IAD, by thought it a tad much for anyone already accustomed to the airport. I also don't think I'd value much an escort to the Skyteam lounge in LHR, though I happen to really like that lounge, equal to the UA one at LHR and better than the BA business class lounges. I only get the AF La Premiere buy-up offers IAD-CDG, not the return. Though I've heard others get them.
