Sit on the Right side of the plane for the best views on flights from Lisbon to Brussels. Right-side seats capture the more dramatic geography: Lisbon's river and bridges during departure, then the Loire Valley and French river systems during cruise, and finally the approach to Brussels. Left seats see less distinctive features during the middle portion of the flight.

During takeoff from Lisboa (LIS), sit on the Right side for the best views. Lisbon typically departs runway 03 (northeast) or 21 (southwest). Right-side seats offer views of the Tagus River estuary and the city's western districts during initial climb. The river's distinctive wide mouth and the bridge structures are clearly visible from 3,000–8,000 feet. Notable sights include: Tagus River estuary, 25 de Abril Bridge (suspension bridge crossing the river), Cristo Rei monument on the south bank, Belém district waterfront.

When landing at Brussels Natl (BRU), sit on the Left side for the best views. Brussels typically lands runway 25L or 07R. Left-side seats during approach offer views of the Meuse River valley and the Belgian countryside south of Brussels. The flat terrain and patchwork agricultural fields are distinctive, and on clear days the city itself becomes visible during final descent. Notable sights include: Meuse River valley, Belgian agricultural plains (patchwork fields), Brussels city center skyline, Atomium structure.

The flight from Lisboa (LIS) to Brussels Natl (BRU) takes Approximately 2 hours 15 minutes.

The flight path crosses the Bay of Biscay, then enters French airspace over Aquitaine. Notable features include the Loire River valley (visible around cruise altitude as a silvery line threading through green plains), the Massif Central as a distant elevated plateau to the southeast, and the Seine River valley approaching the Paris region. The transition from Atlantic maritime climate to continental European landscape is gradual but visible—coastal marshlands give way to dense agricultural regions and scattered forests.
