We flew to Paris on Delta and returned on Air France. Both economy but we had two different experiences. The flight back our seats were way back, the two seaters with extra room on the aisle. We found we had more leg room on this plane. The flight attendants were very nice and attentive. The food was excellent in comparison to what we were served on the Delta flight. The only negative was that we had to pay an extra fee to get. An assigned seat. All in all it was a pretty good experience.
