The students were on a three-day trip that was to include a rafting excursion and a visit to a Six Flags theme park.
The students were then put on other flights, but it took 12 hours for some to reach their destination via transfers that took them as far out of their way as Milwaukee, Wis.
Some of the students posted pictures and video of their journey on social media sites. At least one sent a barrage of Twitter messages to media organizations, complaining that the way they were being treated was a “scandal.”
Linfield said Southwest Airlines offered vouchers to future air travel to faculty and students who were on the plane.
