From the EK website ‘Wheelie’ bags - Please note that rolling bags with built-in wheels and retractable handles will be permitted as cabin baggage only if the total dimensions (length, width and height) add up to less than 45 inches (114 cm). The larger, overnight models of this type of bag will not be permitted in the cabin.

I measured my bag and it comes out to 47 inches overall 21x16x10... Will they give me a huge problem with this?
