The current macro-economic environment, especially in the U.S. is not helping. BA likely lost a small but important leisure market to the U.S. for political reasons. They also tried adding new direct routes to small U.S. hubs (e.g. Nashville or New Orleans) which they are realizing are not as profitable anymore. My best guess is that if there are any route to be announced in the future (assuming the macro-economic environment improves), it will likely be South America/Caribbean and Asia where BA has seen the biggest growth over Q1 2025, notably premium seat demand for the Caribbean and Asia have seen massive growth.
