Yes and no. Short call start times are a big wild card. Last week the most senior guy in the bucket had a raw of 10 due to 2 short calls. He was the 3am guy and got called at 4am for a 7am show for a 5 day trip. There were several junior guys on short call who were also good for a 5 day trip but their SC contact time didn't start until 8-10am so guess who got the trip, yup, the most senior guy. I could give you a dozen more examples where a senior guy will fly before a junior guy but I am late to meet my girl for happy hour. Again, bucket is just a tie breaker if all else is equal.
