Nope.

With longevity pay one bids the airplane, domicile, or type of flying they want without regard to income. Longevity pay allows IPA pilots to have the highest weighted average top-of-scale payrate in both seats per the Delta 2018 Contract Comparison.

Of course, payrate certainly isn't everything when it comes to a contract but IMO there are significant benefits to having as many pilots as possible in as high a given payrate as possible.

I do understand the QOL arguments against it though, because if I were at Delta I'd most likely try to stay on a small narrowbody (assuming the schedules were acceptable) in order to maximize seniority.

There's enough differences between the nature of flying at Delta and UPS that making a direct comparison on many things is difficult.

I say go get yours, whatever that may look like..."A rising tide raises all ships"
