Diff types of Next Day Air and also residential NDA stuff has a longer window to be delivered by.... Commercial NDA stuff has a earlier window.. this is for domestic stuff....
International might be diff
No, the same applies for international (ie. you are correct). The residential commit times are good point, I do most of my interaction with UPS commercial account, so that is what I am used to. However, residential times maybe later than the published commercial times, but I believe UPS breaks this out somewhere. In my market, res and com NDA times are the same - 10:30. Of course, the airport is only 10 min from my house!
