We're going to Spain in late October. The flight home we like best, from Madrid to Detroit, lays over for an hour at Paris' Charles De Gaulle. There are later flights that lay over in Chicago or JFK, but the timing isn't as good. We really don't want to get stuck if flights are delayed/cancelled (need to be at work the next day). I realize that this is probably a question that requires a crystal ball, but does anyone have thoughts about whether you are likely to experience more cancellations/delays at Charles De Gaulle vs. at a US airport?
