Hate to bump the thread, but I find myself flying EI for the first time (first European LCC ever, actually) tomorrow SXF-DUB.
I will have my standard TravelPro carry-on that is within regulation size, but I also want to bring my backpack (normal size) that contains laptop, noise-canceling headphones, meds, etc. It won't be that heavy.
Does anyone think these two items will cause an issue?
