My dd is travelling overseas next month for a dance competition, and this has been all over the message boards about United. Typically, dancers have been able to bring their dresses on as carry on (flat triagle bags that stack very nicely in the overheads). Now this seems to be no longer the case. These dresses average about $3000, so no one wants to check them (and even if they just got lost, one couldn't dance without it). Hopefully someone will come up with a carry-on solution for us (right now the plan B is to have the dancers wear the dress, and then take it off after boarding).
