No, you said, " This is actually one place where DL miles have not lost an immense amount of value" which is just WRONG. It's 3k miles plus a 60 day advanced purchase, not to mention that 125k only existed seemingly for a few minutes........
So it is actually 38k PLUS
A sixty day advance purchase AND
Rarely available, I would posit maybe 3% of the time, while the 125k was available half the time, AND
If you are buying tickets in the other direction, the fees etc have multiplied by a factor of 3 - 7x.....
So I would say that they have in fact lost a great amount of value, and that value is far greater than................3k.
Again, you are the one who brought this up!
