I've done several - maybe 7 or 8. Nothing to get exited about, other than being on the first scheduled flight. Usually a little reception at the gate, maybe a knick-knack souvenir, but the onboard experience is usually pretty normal. Best one I ever did was with my then 6 year old son. The marketing director (Jacqui?) and first class flight attendant (Duane) made my son feel pretty special as the unofficial first Boston passenger when we arrived in Boston.
