Evoc Road Bike Bag Pro - Handlebars on

My biggest concern is the size. Southwest specifications is that L+W+H must be <100 inches and this one comes in at 108". My TT bike is so difficult to take apart that keeping the handlebars on is ideal. I could ship my bike via tribike transport, but then you have to trust someone else to get all the bolts tight and right.
Has anyone had this rejected or been charged a lot with this case?
