The new route is still on the website for May 26 but the flight is now gone for booking on that day and random days I searched in June too

Feels like it is gone. Thanks for the advice, I am going to hit a cruise and a little taste of Oktoberfest (I know not official since not in Bavaria, but still closer than USA)....but with cruises cancelling/ changing daily sounds like I should wait until closer to move to more optimal routing in case I need to cancel and use this to get a full refund.
