1. American Airlines.
3. Basically 2-on, 2-off or 3-on, 3-off if there is a three day trip. At least that was the plan. Reassignments and LA's well published radar problems have driven most AA MD90 pilots up to contract maximums.
4. 3-on, 2-off, 4-on, 3-off, etc., etc., etc. Many competing priorities so that may change depending upon what trips become available for possible trade(s).
AA MD90s operate in California Corridor only so we behave similar to commuter carriers (with better contract limits). 3-6 flights per day average with about 1 to 1+15 gate-to-gate times.
