What is the best way to keep the quality of fried food? was recently closed as a duplicate of Best way to hold deep-fried foods?. However the former is asking about storage methods of still hot food for delivery and the latter is asking for cooling, refrigerating and reheating instructions.
This is a very good catch, thanks! I didn't notice the difference when closing the question.
If that was all we have in duplicates, I would be OK with reopening. However, we also have at least three questions on transporting food while keeping it crispy: How to keep fried fish warm and crispy during transport to venue?, Crispy fried chicken goes limp: picnic disaster and How to keep my pizza hot and crispy during transport. I actually think we must have more, they just didn't turn up using the search query [transport crispy].
It is true that the OP in the closed question asked for French fries, but none of the answers in these questions are specific to the food being transported, and I don't see much value to the site in keeping the answers strewn under different questions just because the name of the food is different. Since closed duplicates are not deleted, the next person seeking how to keep French fries crispy will find the information easily if the question is closed as a duplicate of one of those.
So my suggestion here is to reopen and close it again as a duplicate of the fish question, which seems to have some nice sugegstions in the answers. I won't act on it though until this Meta question has had time to gather some alternative answers and votes.
