KLM Royal Dutch Airlines is consistently rated as one of the best "legacy" carriers in the world, known for its reliability, excellent customer service, and its massive, efficient hub at Amsterdam Airport Schiphol. As the world's oldest airline still operating under its original name, KLM has a reputation for a high "safety culture" and a very modern fleet, including many fuel-efficient Boeing 787 Dreamliners. Passengers in Economy often praise the airline for its "European charm," which includes complimentary snacks and drinks even on shorter flights and friendly, multilingual cabin crews. In 2026, KLM is also a global leader in sustainability, heavily investing in Sustainable Aviation Fuel (SAF) and its "Fly Responsibly" campaign. Their "World Business Class" is highly regarded, specifically for the iconic Delft Blue miniature houses filled with gin given to passengers as a souvenir. While Schiphol airport has faced some congestion challenges in recent years, the airline's operational "on-time" performance remains strong compared to other European giants, making it a top choice for transatlantic and intercontinental travel.
