According to CNBC, J.D. Power's annual North America Airport Satisfaction Study found that overall airport satisfaction rose significantly this year, marking the third straight year of gains. The report, released Wednesday and based on responses from more than 24,000 travelers, said higher ratings were helped by newer gates and terminals opened in recent years. Among airports handling more than 33 million passengers annually, Minneapolis-Saint Paul International received the top score. Tampa International ranked No. 1 among airports serving 10 million to 32.9 million passengers a year, while Charleston International in South Carolina was rated the best among medium airports serving 4.5 million to 9.9 million passengers annually.
