OP - No. This is one of the many ways DL shows it's disregard for segments qualifiers. Our segments die, rather than roll over. For some reason, despite the fact that we now know that segments qualifiers spend more than miles qualifiers, we are treated as lessers when it comes to rollover. Our segments don't count extra on expensive tickets, despite the extra MQMs for the same flights, we don't qualify for credit card bonus segments, despite MQMs being offered and we aren't able to purchase a couple extra segments at the end of the year if we are close, but not quite there.

I did stop short one year, but ultimately qualified the next year on segments, rendering stopping moot. Don't do it. You'll regret stopping short. You'll wind up having to do your 100 segments for next year and won't have anything to show for the rollover. I learned that lesson, and am planning to pass the 140 mark this year.
