I did some preliminary checking of airfares last night, using the equivalent dates for 2017 since it's too early to see prices for January 2018. As we feared when the extremely early schedule was announced, it appears that those of us who go to Nationals early (in this case around New Year's Day) are going to be paying extra for the privilege, at least $100 more than the usual fare from the east coast. Other early birds might want to take a look at 2017 fares from their home airports so they'll have an idea what would be a relative bargain and can watch for fare sales or buy early if the price looks good.
