Thank you for your very helpful post re: ATL to CDG. We are traveling to FCO to pick up a cruise at the end of July and the cruise terminates in Cannes. I'm looking into europebyair flight passes from Nice to Brussels to avoid the CDG hassle. We still need to better our chances of getting back within a two day window. My question is (and this might be duh, but haven't bought ID 90's before); what is the advantage of buying ID 90's/95/96 as a 'backup' if they're still stand by? We're traveling on S-2's or S-3's depending on the loads.

Thanks so much.
