I'm going on my first plane ride with LO in a couple weeks. Our flight is out early in the morning so taking public transit is not an option. On past trips DH and I take a cab, but for some reason getting from Somerville to Logan is expensive ($50 each way). So, I briefly looked at long-term parking at Logan and it looks expensive. We could do a cab again, but I worry about being able to install LO's carseat. Some cabs we've taken are hella old and honestly the drivers can sometimes be scary drivers.

Thoughts? What have you done?
