Airport Charging Etiquette

Ok to plug in and fly off?

  • Total voters
  • Poll closed .
What is the consensus on charging while at the airport? I use the reserved parking at our local airport. I see cars parked in the dedicated charging spots, charging, when I depart and when I come back days or weeks later some of the same cars are there. I’ve avoided plugging in even when I have desperately needed it because I would be occupying a space well beyond the time needed for charging. Everyone who parks at the airport will obviously be gone for some fair bit of time and leave the vehicle unattended. What is the consensus on approach?
The airport charger I plug into is located in LONG term parking. Long term is identified as anything longer than 24hrs.
In addition, there is now one charger for 4 parking spots. The thought is that the charger will be shared and that new arriving EVs will unplug cars that have finished charging and help themselves to an idle charger.

SeaTac has a row of charging spots with 120V wall plugs, where EV's plug in for days at a time. I've never used it, as I can easily make the round trip (under 100miles, plug few miles per day loss) but drive by to see it a couple of times and they are usually full (I saw a spot open once or twice) so can't really count on it anyways.

Airports should really operate a ‘charging service’ is where they have your keys and top you up periodically then fill you up for the drive home.

I know there are some already....
I strongly suspect it would be cheaper to simply provide a large chunk of spaces with 120V outlet meant for long term charging. One time cost to wire them up and done. 100 spots with 1.5KW charging is 150KW total, not huge for an airport and I bet they would rarely peak too, with cars parked there for days probably not even half would be charging at any time. They could even charge extra for parking to cover the costs.

SeaTac row of such wired spots is always full because:
a) there aren't that many spots
b) they are too close to the terminal (easier to wire power?), essentially premium parking and I suspect some people use it as such. Found this photo on plug-share. I wonder how many of these really couldn't make a round trip to the airport.

A large swath of such parking spots in the farther corner of the covered parking which usually has open spots anyways would probably be the best solution.

I think that it depends on the airport and type of charging. In ATL I park at Peachy Parking and they have specific EV Charging slots and specifically advertise the service. There are a few other off-airport facilities that have charging, but some of them will cycle cars off the chargers as needed.
I would never expect to stay plugged in for a week at airport short term parking. At long term airport charging, I would tend to stay in, because why else is it there?

The one thing that I tend to hate is the hybrids that plug in at long term parking. Up until recently I drive a 2015 Leaf, I HAD to charge at the airport, at 55 miles one-way, I couldn't get back home otherwise. With my 2018 Leaf, I can do it, but I don't have much spare charge left. With the Model 3, my biggest need is for long term to keep the phantom discharges from killing me. (The Leaf doesn't have this).

at MSY I've never seen the charging spots full, so I assume they're not used that much. never take longer than 4-5 day trips though so I usually plug in and charge to 70%, then on my flight home I set to 100% for range charge.

I remember ATL airport had dozens and dozens of chargers in empty rows at the long term parking, and their chargers are purposely slow (I think I was getting like 8mi/hr (3kw) charge rate) probably due to long-term parking usage.
