It seems to me that if there's still "whining" after 22 years, the arbitrator did a lousy job of merging your lists.

The Western and Pan Am pilots were merged by relative seniority, by equipment. This protected everyone's position; there were no major upheavals, no one's career suffered, and there were few hard feelings. We certainly don't have separate camps of pilots within Delta, with none trusting the other.

Which group you're in- Original Delta, Pan Am, or Western, doesn't even merit a mention in the cockpit. It may come up in conversation, or it may not. Either way, it's a non-issue.

If you think that disparate pay was a complicating factor in the merger, consider that, at the time of the Delta/Western merger, a Delta L1011 engineer earned more than a Western DC10 captain. There were some problems (the Western guys' pay came up in stages, rather than at once; a bad policy, IMO), but overall, we became one team after the merger.
