For most res the option is not there or clicking change just says that cannot. And if can....oh boy, that's like playing Russian Roulette with live bullets: there is a strong chance your whole ticket will be nuked with no notification, no refund, nothing, and then many hours afterwards on the phone with endless escalations and in the end some 6 or 8 Delta people working on it to try to reinstate it. Not worth it to ever touch that "change" button. Far too dangerous. (Though to be fair, recently no reservations nuked by that for me...but then again I know better than to go too far in the process the few times when it works.)
