My guess is no, but it could be down gauged (depending on schedule and positioning issues) to a 757 with BE and ETOPs and if IROPs occur (mechanical, weather, ATC delays, etc.), the load could be a factor in the decision of what to do.

You might want to investigate loads on other days and draw your own conclusion about whether the flight is likely to be suspended or discontinued from the schedule (not just on your flight date). Right after the merger, the MSP-CDG nonstop was suspended in the middle of the summer, rather than continuing the seasonal schedule until the fall as announced and planned. Remember, however, that the profitability of the flight is what matters, not just the number of occupied seats. Also, there could be an agreement about service or subsidies at CVG. (PIT is known to have such an arrangement for its DL TATL nonstop.)
