: In our case, we want people to be able to change the symbol sizes (eg. you need to fit in more content in to a header). If you need to resize or accidentally resize something, Sketch (<3.5) would automatically resize every instance of that symbol. That would kill your sketch for few moments and probably mess up your file permanently (sometimes undo didn’t work). We ended up putting the components in Layer Groups, and letting people copy and paste them.
American Airlines allows all passengers to bring one carry-on bag and one personal item on all flights. The maximum dimensions for personal items are 18x14x8 inches and must fit in the seat in front of you. Certain infant necessities and medical equipment are also allowed as needed. Carry-on bags may not exceed 22x14x9 inches and must fit in the sizer at the airport. Bags that do not fit in the overhead bin or under the seat will need to be checked.
