Finland topped the World Happiness Report for a ninth consecutive year, while the US ranked 23rd. US air travelers face long security lines due to TSA workers missing paychecks amid a partial government shutdown, and global airfare prices are rising due to fuel cost increases driven by the war with Iran.
