Yes, or indeed don‘t take for granted that other buckets are non-flexible. I used to regularly buy semi-flexible tickets in i or A class which were changeable for a nominal, sometimes small, fee. As you go „up“ the chain though, availability changes, and a flexible ticket in a class that‘s not available on a particular flight you want will not help you.
