Simple question, I hope. I have HEL-GDN scheduled later this year, which is an N7 ATR-72/500. My flight in will be DUB-HEL HBO with an overnight stay, so I'll be returning for the ATR leg from a wander and store my bags at the hotel. When I return to HEL, how do I handle my standard size carry-on wheelie? Do I check it before security, or at the gate?
