I'll be flying CO BF next month, CDG-IAH and have noticed that, more often than not, the flight has been departing from gates 37-39, instead of 48-52. The skyteam website lists only one AF lounge in 2A, near gate 52. Is there another option closer to gates 37-39? If not, what lounge would I use? I know there's an AA AC out there, but don't think a CO passenger, even in BF, would have access, n'est-ce pas? And I sure don't want to walk from gate 52 to 37 since that involves going up and down a significant set of stairs in the middle of 2A which would be somewhat difficult for me since I'm moderately mobility challenged.
