"UTA undertook this as a way to promote our new airport extension to the TRAX green line," said UTA spokesman Remi Barron.
"We see this as a good way to reach out to new customers who might not be heading out of town" at the airport, he said. "It is the first year that people can ride TRAX all the way to the fairgrounds." The green line opened in April.
The UTA also is giving away 25 passes to the fair each day before the fair opens. It distributes information about where it will hand out those tickets on its Twitter account.
The fair opens Thursday and runs through Sept. 15. The fair opens at 10 a.m. and closes at 10 p.m. on weekdays and 11 p.m. on weekends. While TRAX service is offered during most of those hours, the last green line train from the Fairpark Station is at 8:06 p.m. on Sundays hours before the fair closes those days.
