The express bus to Incheon Airport

ESL TEACHERS: There is a bus from Yeonggwang direct to Incheon Airport. Unfortunately it only runs twice a day to the airport and twice a day back to Yeonggwang. The fair is 29,000 Won each way. The ride takes about 4 hours depending on traffic.

I'll have to confirm this, but I think the poster below tells the bus times. The departures to Incheon are 03:20 and 9:30. The return options are 08:40 and 18:20. I expect to be taking the 03:20 bus when I go to China in August so I'll update this if I find any errors.

This is a poster in the Yeonggwang terminal.
