Green Line will give you a ride to the airport
Since I moved here, I've always taken the bus to the airport. I just can't see making someone take me or paying for parking when I can pay the $1.25, lug my luggage (albeit, a little awkward depending on the time of day and how many folks are crammed on already) onto the No. 8 bus, sit back and arrive at my destination without a whole lot of fuss or hassle.
But this week IndyGo launched the Green Line Downtown/Airport Express, which stops at a slew of downtown hotels and provides non-stop service to the airport. Of course, it costs $7 instead of $1.25, but for non-stop service and more frequent runs (and luggage racks!), it might be worth it.
Full details here.
