If they put the charging stations in LONG TERM sparking at the airport, I can’t see how there would be any expectation that you move your car after a couple hours. Park there for your week-long trip and enjoy the charging perk. I’d set your charge level to 90% (or below) when you park, possibly use the app to bump the limit to 100% when you pull away from the gate at your last leg on your return trip home, turn on the heating and cooling as soon as you land…
Based off the comments on PlugShare, don’t be surprised if all spots are full or only broken spots remain open.
