Sit on the Left side of the plane for the best views on flights from Miami to Barcelona. While the right side wins at takeoff for Biscayne Bay views, the left side delivers more consistently across the full flight: it faces south over the Atlantic during the transatlantic crossing, then picks up the Iberian Peninsula coastline, and finally offers the best view of Barcelona on approach. The right side is mostly open ocean for the bulk of the journey.

During takeoff from Miami International (MIA), sit on the Right side for the best views. MIA typically departs east on runway 09 or northeast on runway 12, meaning the right side faces south over Biscayne Bay, the Florida Keys chain, and the turquoise shallow waters of the Florida Straits. The left side gets the urban sprawl of Miami inland. Notable sights include: Biscayne Bay, Virginia Key and Key Biscayne, the Florida Keys chain stretching southwest, Port of Miami cruise terminals.

When landing at Barcelona (BCN), sit on the Left side for the best views. Barcelona's El Prat airport typically lands from the southwest on runway 25L/25R, meaning the aircraft approaches over the Mediterranean from the south. The left side faces north toward the city of Barcelona, the Sagrada Familia district, and the Collserola ridge behind the city. The right side faces open sea. Notable sights include: Barcelona city grid and waterfront, Montjuic hill, the Collserola ridge (Serra de Collserola), the Llobregat river delta.

The flight from Miami International (MIA) to Barcelona (BCN) takes Approximately 9 to 10 hours.

The flight tracks northeast across the Atlantic, passing north of the Bahamas and Bermuda, then crossing the Azores archipelago (visible as small dark volcanic islands in the mid-Atlantic if routing passes nearby), approaching the Iberian Peninsula near Lisbon or the Algarve coast of Portugal, crossing over southern Spain including the Sierra Morena and the Ebro basin before descending toward the Catalan coast.
