Ever flown out of San Antonio? Then you’ve flown out of the sixth-worst airport in the United States, according to a new study.

Credit card site Upgraded Points analyzed 60 of the biggest airports in the country and deemed San Antonio International Airport particularly unsavory. The study compared the airports in terms of overall satisfaction, flight delays and cancellations, ease of access to the city and airport amenities -- and San Antonio ranked particularly low in almost every category.
