The site says, "Join us today and expect to earn a minimum of between $260,000 - $317,000 in the first three years and even more by upgrading to Captain!" When you click on the breakdown though they also include medical and dental and life, per diem and the 401k in total compensation. If you take those out that decreases the 3 year compensation by about $45k or so.

But they show base pay for the 3 years as $35k, $56k and $74k.
