To find out more about a multi-destination ticket, I recently went to the SunExpress Airlines Helsinki Office. My options were thoroughly explained by the staff, who were quite accommodating. They also offered advice on how to get from the destination airport to local transportation and reasonably priced upgrades. It was a really good experience. The entire procedure felt very genuine and intimate, and the service was timely. Online portals don't offer this caliber of service. I heartily endorse them.
