I think we're all flying fools, but good of you to label yourself! I just flew with my husband on 3 trips and suddenly realized I only have 5 transoceanic legs left (out of 18!!) with 4 months to go until anniversary date--ACK!!! AND, we already have 2 vacations scheduled to use 4. Guess I need to pay attention to our account! I wish you that dilemma some day! hahaha

What about taking Delta from DCA and catching something from JFK (a flight, silly...) that will turn around back to cvg? If you do--make sure you take paper passes with you!
I don't know if $80-$160 plus us fees is worth the fuss? You could hit CDG. There have lots of employees and buddy passes in BE on my last few trips--sure beats sardine class!! Just an idea, since you're already in dc...
