Forced checking of legal-sized carry-on?
I'm planning a trip to South America (EZE), carrying both camera and computer equipment in legal-sized carry-on luggage. We'll be traveling in Business on a 777.
Is there any likelihood that the gate agent will make us check these carry-on bags? The reason I ask is that these items are fragile and I really don't want them checked.
I've read the threads about over-sized "carry-on" luggage, but I couldn't find an answer to this question.
