You will if it's bigger than the alliwed hand baggage size. It'll depend on the boarding team and how strict they are though. If it fits the box at the boarding gate and there is not enough place fir bags at the racks, if you are boarding last it's probable that they ask you to check it, in this situation they won't charge you. Companies have different policies about baggage, and even inthe same trip you may have problems if a leg is operated by a low cost. Even if the ticket was bought through the main carrier. I take planes more than 15 days a month and I've seen all this happen.
