IMHO, it's because the software engineer who wrote that program read the FARs and didn't under stand it's not the end of the world if you go a few knots above 250 below 10. As someone else alluded too, I completely disagree with the company position. Standard maneuver tolerance is +/- 10 knots. If we are supposed to be flying 250 and the airplane is flying a perfect 240, fine. But when it slows below 240, as if often does, you are not in compliance with your assigned speed. I try to remember to set the FMS to fly 250/10000. If I forget, as soon as I go below 10,000 I speed intervene 250.
some of the old head 767 guys who are gone, like BW and CT thought it was sacrilege to reprogram the box for 250. They were wrong and I don't know anyone who still teaches to leave it at 240.

If there was going to be a 787 order, I'd say the current Boeing woes would've been more than enough reason to postpone declaring one. I could see us eventually placing one just like with our other recent fleet additions, pending MRO rights for the engines... but only if Boeing gets their act together.
And I know the 777 was the best airplane since the 757, but it also wasn't nearly as efficient. Management has stated before that the 777 has has half the CASM of an A380 but the A350 has half the CASM of a 777. I don't know how accurate that is, but that was the management line. Regardless, even the mighty 777LR had trouble with JNB-ATL and going full.
And there is one thing that no one can realistically argue. I might not always agree with our management on their decisions... but they know how to make money and lots of it. Sure there are missteps, including ones we all seem to see clear as day, but overall I am confident we are the best run and I wouldn't trade that for my seniority at any other airline.

With the 737, it allows you to deploy flaps without opening the speed window, you can let the FMS manage all your speeds from takeoff all the way to touchdown. On climb out you don't need that because it won't go above 230 until the flaps are fully retracted, but if you had 250 below 10 you wouldn't be able to extend flaps without opening the window.

It’s something that makes us better than all the other 737 operators, or not.

It has been a few years since I flew the 717, but you could also program the FMS in the descent for 255, and the box will assign five knots less, leaving you with a magenta ball at...250 KIAS.

This isn’t a software engineer overthinking it…it’s Delta stupid. Other 737 operators default to 250 below 10. It’s just some OCD Delta thing, just like the previous issue with using the rubber bands for hot mic and folding the checklist into quarters.
