I'm getting a decent price for PDX - BCN - CDG, $1115 for June, but the CDG one hour layover is a deal killer. Or is it?
Where do I look to find if there is a terminal change?
The next flight to Barcelona is 3 hours later.
I guess I'm really asking if those of you more experienced and frequent travelers would take the risk.

Most, if not all, AF flight from the US arrive at 2E. Flight to BCN departs from 2F. You also need to go through immigration and security.

You are thinking that your flight will arrive on time, that folks will exit in record time, the bus to the other terminal will be waiting for you, etc. We missed our connection with 1hr. 10 min. turnaround. Security lines were LONG, plane was a bit late in arriving and it took forever for folks to exit. Take the 3 hours.

Thank you for the reality check. Needed that.

Agreed. I've tried this a couple of times in the past, and wound up missing my flight. Fortunately, AF moved me to the next flight. The extra time is worth it.
