I'm booked on an intl flight to CDG next month. My domestic flight arrives STL 1 hr 12 min before my STL-CDG flight departs. I see that STL's minimum connecting time domestic to intl is 45 min, and my flight to STL has an 80% on time rate, but I'm still concerned. TWA has no flights to CDG after my 7pm flight, so I'm wondering, if I don't make it due to a delay on my domestic portion, what action is TWA likely to take? Any advice appreciated.
