Seems like a lot of attachments to need on a plane but to each there own. I have the 13" macbook pro (it sucks) but I use a
purefix dual USB C dongle to handle all connections. Perhaps they have a single USB C adapter. But I have found a good laptop bag (swiss gear) with external access works well. Just a long USB-C cable and a dock/hub in my bag with everything attached in the bag works well. I keep small pouches with spare cables, storage and chargers but it is all stored in the bag.
