About
KAYAK is a travel metasearch engine founded in 2004 by Steve Hafner and Paul English, acquired by Booking Holdings (then Priceline Group) for $1.8B in 2013. Headquartered in Stamford, Connecticut, KAYAK aggregates flight, hotel, car rental, and vacation package results from hundreds of travel sites, enabling one-click comparison shopping. Its product suite includes KAYAK.com, the Momondo brand (acquired 2017), HotelsCombined, and a business travel management platform, KAYAK for Business.\n\nKAYAK's revenue model is primarily CPC (cost-per-click), charging airlines, OTAs, and hotels for qualified referrals rather than taking a booking commission. This metasearch model positions KAYAK as a neutral aggregator rather than a competing OTA, though it also offers direct booking through its platform in select categories. KAYAK for Business targets corporate travel managers with policy controls and expense integrations.\n\nAs a wholly owned subsidiary of Booking Holdings ($26.9B revenue FY2025), KAYAK does not report standalone financials. It remains one of the most visited travel websites globally, with over 300 million monthly searches across its brand portfolio. KAYAK's AI trip-planning features and integration with Booking.com inventory have strengthened its position as a one-stop travel research tool heading into 2026.

About
Delta Air Lines was founded in 1924 in Macon, Georgia, as a crop dusting operation, and has evolved through a century of consolidation, innovation, and reinvention into one of the world's premier airlines. Following its emergence from bankruptcy in 2007, Delta executed one of the most successful corporate turnarounds in aviation history, becoming the industry's most profitable and operationally reliable major carrier. Delta's mission is to connect the world with excellence, safety, and authentic hospitality.\n\nDelta operates a hub-and-spoke network from primary hubs in Atlanta, New York (JFK and LGA), Seattle, Los Angeles, Boston, Detroit, Minneapolis, and Salt Lake City. Its fleet of 900+ aircraft serves 300+ destinations across six continents. Delta's premium cabin strategy — expanding Comfort+, Delta One, and Delta One Suite offerings — has been a key revenue driver, along with its co-branded American Express card program, which generates billions in annual revenue from card spending and miles redemption. The SkyMiles loyalty program serves over 100 million enrolled members.\n\nDelta reported FY2024 revenue of $61.6B, a 6.2% year-over-year increase, with net income of $3.5B and service to 200M+ customers. EPS guidance for 2025 exceeds $7.35. Delta's operational reliability, premium brand positioning, and diversified revenue streams from loyalty and ancillaries have made it the most consistently profitable U.S. airline over the past decade, and a benchmark for operational excellence across the global aviation industry.
