Ditto, not a lawyer, but been through this mill.
Another point to consider, is that a financial settlement is done on assets available now (at this point in time), then divided based on assessed contributions - both pre relationship, during and post.
There is no expectation that your life is frozen post separation, so absent "waste" or other unreasonable running down of assets, what is expended between separation and settlement is simply gone. If there is some degree of unreasonable wastage, then a court will adjust the division of what assets are available to take account of this.
In your case, as the points no longer exist, the question is more about what they were expended on. If the trip is a reasonable part of continuing with your normal life, and perhaps the alternative would have been spending money you were earning rather than using points, then the most likely outcome should a judge get to it, is that the points issue will be irrelevant, and be ignored.
I must, however, echo previous posts - trust your lawyer, not random advise from people on the internet (no matter how knowledgable they appear

), and try and reach an appropriate settlement, rather than handing it all to those same lawyers.
