I would pay for the FCO-PMO flight, maybe CDG-PMO flight, if DL just had low BE award inventory from SFO-CDG or SFO-FCO.
It keeps showing a SFO-SEA-CDG route for $100k but when you try to book it, says one of the flights sold out. Then you search again and it comes up again.
It's been like this for a couple of weeks. Maybe a sign that eventually that inventory will be available.
