Sit on the Right side of the plane for the best views on flights from Key West to Cancun. Right-side seats capture the most dramatic geography: the Florida Keys departure and the open Gulf of Mexico crossing, plus on approach the Caribbean's color gradations and reef systems are equally striking from either side, but the outbound Keys view tips the advantage right.

During takeoff from Key West International (EYW), sit on the Right side for the best views. Key West typically departs runway 09 (westbound) or 27 (eastbound). Right-side seats on either departure offer views of the Florida Keys chain extending northwest, plus the shallow turquoise waters of the Gulf of Mexico. Eastbound departures (runway 27) give the best right-side perspective of Key West town and the reef systems. Notable sights include: Florida Keys archipelago (extending northwest), Gulf of Mexico shallow banks (bright turquoise), Key West town and harbor (directly below initially), Marquesas Keys (visible as small islands to the northwest at distance).

When landing at Cancun International (CUN), sit on the Left side for the best views. Cancun typically lands runway 07 (eastbound) or 25 (westbound). Left-side seats on approach offer views of the Yucatan Peninsula's Caribbean coastline, the Hotel Zone's distinctive beachfront development, and Nichupté Lagoon. The turquoise Caribbean waters and reef systems are particularly striking on descent. Notable sights include: Cancun Hotel Zone beachfront (linear development along coast), Nichupté Lagoon (large shallow lagoon system), Caribbean Sea reef systems (visible as color variations in shallow water), Yucatan Peninsula jungle (dense green inland from coast).

The flight from Key West International (EYW) to Cancun International (CUN) takes Approximately 1 hour to 1 hour 15 minutes.

The flight crosses the Straits of Florida and open Gulf of Mexico waters. At midpoint, you're roughly 80-90 nautical miles southwest of Key West with no land visible—only open water. The Yucatan Channel (deep water between Cuba and Mexico) lies to the south but remains below typical cruise altitude visibility. As you approach Cancun, the Yucatan Peninsula's northern coast becomes visible, with the distinctive turquoise shallow waters of the Caribbean marking the approach zone.
