Whether First Class is "worth it" on the Bernina Express in 2026 depends heavily on your desire for space and panoramic photography. The most important fact is that the panoramic windows are identical in size and quality in both First and Second Class. However, the seating configuration is the primary difference: First Class offers a 2+1 seating arrangement, providing much more elbow room and a more private atmosphere, whereas Second Class is 2+2. For photographers, the "1" side in First Class is highly coveted as it allows you to sit alone and move easily to capture views on both sides of the train. The First Class carriages are also generally quieter and less crowded, which can make the 4-hour journey from Chur to Tirano feel more relaxing. That said, the "scenery" is exactly the same, and if you are on a budget, the Second Class experience is still exceptionally high-quality compared to standard trains. If you value personal space and a slightly more "exclusive" vibe, the surcharge is justified; if you just want to see the Alps, Second Class is more than sufficient.
