AA still flys direct into EIS via Cape Air and Seaborne. More expensive than into STT but I figure my time is worth it. It use to be that I could get from Seattle to Eis leaving at 11pm Seattle arriving noon in Eis next day. Now we do not get in until 4:30 pm. Not horrible but I would prefer the earlier connection.
You should be able to leave DFW early am and be in EIS by late afternoon
