Thanks RteSmrt. My flight to LIS is all on Delta through CDG. It only lists one terminal, so I'm not sure if I'm switching or not. I made the assumption that it was the same terminal for both flights or is just listing my arrival terminal.

The other flight from IST to DUB through AMS was booked through Delta but is a KLM flight with a 1 hour in AMS.

I'm planning to carry my bags, so I'm hoping that will save some with finding luggage. Depends on the size of bag I will need for this flight.

I'm also concerned with all the labor stuff going on in France. I'm not sure I want to pay the change fee at this point, but I suppose I should call Delta and see. Just seems wrong that they offer flights with such tight connections if it's an issue.

Thanks again for your help and let me know if there is any other suggestions you have.
