A Pro Tip for Finding Cheap Flights to Vegas
Before we dive into the airlines, here's a crucial hack for securing the best deals. Services like Going.com (formerly Scott's Cheap Flights) are invaluable. Simply set your home airport and watch your inbox for mistake fares and incredible flash sales. While the free version is useful, the $49/year premium membership can unlock savings that pay for itself with a single booking—think roundtrip fares like Boston to Las Vegas for just $167. For any frequent traveler, it's a non-negotiable tool.
Top 10 Airlines for Your 2025 Las Vegas Trip
1. 🇺🇸 Delta Air Lines

2. 🇬🇧 British Airways
For travelers from the UK and Europe, British Airways is the premier choice, offering the only direct flights from London to Las Vegas. As a member of the oneworld alliance, it provides excellent connections across the U.S. through its partner, American Airlines. BA is a full-service carrier, meaning even economy passengers enjoy a free checked bag allowance, meals, and drinks. The long-haul experience is enhanced by modern aircraft like the Boeing 777 and Airbus A350.
Loyalty Program: The Executive Club uses Avios, which offer excellent value for off-peak redemptions to Vegas. Points can be transferred from Chase, American Express, and Capital One.

3. 🇺🇸 Southwest Airlines
Southwest is synonymous with value and convenience in the U.S. market. As one of the largest operators at Las Vegas (LAS), it offers an unparalleled domestic network. The airline's core appeal lies in its straightforward, customer-friendly policies: two free checked bags per passenger, no change fees, and famously friendly crews. While it's an all-economy airline, the seats offer more legroom than many competitors.
Loyalty Program: Rapid Rewards is a simple, revenue-based program where points' value is tied directly to the ticket price.
Pro Tip: Book a "Wanna Get Away Plus" fare. The small price increase gives you the flexibility of same-day flight changes and standby, perfect for unpredictable travel schedules.
4. 🇦🇪 Emirates
Emirates brings world-class luxury to the skies over Las Vegas, even on short hops. While its main hub is in Dubai (DXB), Emirates operates a unique "fifth-freedom" flight between Los Angeles (LAX) and Las Vegas (LAS). This short flight is serviced by a long-haul Boeing 777-300ER, allowing travelers to experience international-grade service—including multi-course meals and complimentary beverages even in Economy—for the price of a domestic ticket. Premium cabins feature lie-flat seats and even a chauffeur service.
Loyalty Program: Emirates Skywards points can be transferred from all major U.S. credit card programs, making redemptions on this route an excellent value.

5. 🇸🇬 Singapore Airlines
Renowned for its impeccable service and attention to detail, Singapore Airlines offers another fantastic "fifth-freedom" opportunity for U.S. travelers. While its hub is in Singapore (SIN), you can fly on their Airbus A350 from Houston (IAH) to Manchester (MAN) and connect onwards. The experience is exceptional across all cabins, with chef-designed meals, premium amenities, and a generous 30kg (66lbs) baggage allowance in Economy. Their Business Class and Suites are legendary in the industry.
Loyalty Program: KrisFlyer is a Star Alliance member program with some of the best redemption values, especially when transferring points from partners like American Express during bonus periods.
Pro Tip: Look for connections through Houston to experience their long-haul product. It's a premium way to cross the Atlantic before heading to Vegas.
6. 🇨🇦 Air Canada
For travelers coming from Canada, Air Canada offers a seamless and efficient journey. A key advantage is the ability to use U.S. pre-clearance facilities at major Canadian airports (Toronto, Vancouver, Montreal). This means you land in Las Vegas as a domestic passenger, skipping long customs and immigration lines upon arrival. The airline is known for reliable service, modern aircraft like the Airbus A220, and comfortable Maple Leaf Lounges.
Loyalty Program: Aeroplan is a powerful Star Alliance program with solid redemption deals and flexible stopover options, allowing you to visit another city on the same ticket.

7. 🇦🇺 Qantas Airways
Qantas is the go-to for travelers from Down Under, offering the only direct flights between Australia and Las Vegas. These seasonal flights, typically from Sydney (SYD), are operated on the Boeing 787 Dreamliner, an aircraft designed for ultra-long-haul comfort. The Dreamliner's higher humidity and lower cabin pressure help combat jet lag on the 15+ hour journey. Passengers can expect warm Australian hospitality and a generous baggage allowance.
Loyalty Program: Qantas Frequent Flyer points offer good value when used for these direct flights, especially during seat sales.
Pro Tip: Keep an eye out for the seasonal direct Sydney-Vegas flights, which often align with major conventions and peak tourist season, to avoid a connection in LAX.
8. 🇩🇪 Lufthansa
Known for German efficiency and precision, Lufthansa provides excellent connectivity from Europe and beyond via its hubs in Frankfurt (FRA) and Munich (MUC). As a Star Alliance member, it offers seamless connections to its partner, United Airlines, for the final leg to Las Vegas. Lufthansa's hubs are models of efficiency, and its lounges are a standout feature, offering hot food, barista coffee, and well-stocked bars. The onboard experience is consistent and professional.
Loyalty Program: Miles & More offers reasonable redemption rates and good availability to Las Vegas.
Pro Tip: On long-haul flights, book the "Sleeper's Row" in Economy. It gives you a full row of seats to yourself with a mattress topper and pillow, creating a budget-friendly lie-flat bed.
9. 🇯🇵 All Nippon Airways (ANA)
ANA delivers legendary Japanese hospitality and meticulous attention to detail. Flying ANA transpacific to a U.S. gateway before connecting to Las Vegas is an experience in itself. The aircraft are immaculate, the catering is gourmet, and the cabin crew is proactively attentive. Their flagship premium cabins, "THE Room" (Business) and "THE Suite" (First), are considered among the best in the world, offering unparalleled privacy and space.
Loyalty Program: ANA Mileage Club has some of the best redemption values in the industry, particularly for premium cabin awards on partner airlines.

10. 🇲🇽 Aeroméxico
For travelers originating from Latin America, Aeroméxico offers a fantastic blend of convenience, competitive pricing, and superior service.
