Booked flight no longer appearing in search results

Hi! I booked a flight a few months ago for April 2026. It’s a long International flight. Iberia has added a new route from my destination and has added/cancelled days in which the original route flies.

My booking is still active, but if you search in Iberia the route and day that I have booked, my flight is no longer appearing in search results (only the earlier flight appears). In all booking sites as well. The flight number is different and everything.

I waited to see if it was a system error, but it’s been a month and nothing has happened. I call Iberia and they say there’s nothing they can do since my booking is still active.

Has this happened to anyone before? I buy my award flights with enough time ahead and don’t want an issue last minute, closer to my travel date.
