A:AnswerIm not sure you'll have much luck with any heavy duty thick cases, but I have a Speck clip on case that covers the top and bottom. Im able to use the port with no problems and I can slide the MacBook with the Speck case on it down into a Thule carrying case and just leave the side unzipped if you don't want to unplug it. Hope this helps! I recommend the case and carrying cases I have, but check for your size if you do decide to go with those.
A:AnswerAs long as the MacBook Air includes two USB-C thunderbolt ports, the hub should be compatible. Only the refreshed MacBook Air models released in 2018 and after include the two USB-C ports.
