1. Not really. You've got to understand where that pay rate came from. Essentially, UAL bribed its pilots to acquiesce to the proposed UAL-AAA merger that never happened. Then DAL pilots asked for UAL +1%. The managers were happy to give that rate to get a contract. They could have raised ticket prices $5 to $10 a segment and paid for it.
2. Same as #1. Raise ticket prices and neither of these are factors.
4/5. Gas/TSA charges after 911. Gas? Oh well, hedged airlines did well. TSA? Typical Republican mandate of a gov't program with no funding to go with it.
6. CRJ? Don't make me laugh. Read Mike Boyd's commentary on the CRJ at
