Small ✈️ Airplane emoji is a picture of a compact version of the airspace transportation represented by ✈️ Airplane emoji (although in some cases the main difference is not the size but orientation). Unsurprisingly, both of these emoji are used in the same context — i.e. in various meanings related to traveling by air to anywhere and with any purpose from tourism to business.
Examples of using
“I want my own private airplane 🛩️”
“My next flight is tomorrow 🛩️”
