If you’re searching for United flights to Las Vegas and looking to get the best deal on award travel, you don’t have to look far. In fact, we’ve done some of the digging for you and rounded up six cheap United flights to Las Vegas that will get you the most value whether you’re paying in cash or United MileagePlus miles.

How to know if you're getting a good deal

Since flight prices and award redemption rates change frequently, it’s not a bad idea to know a bit about how to decipher if an award flight is a good deal. NerdWallet values United MileagePlus miles at 1.2 cents per mile. To get the best value when it comes to cashing in miles for award travel, the best deals on award flights will be valued at slightly more than that. To figure out the cash value of an award mile for a flight you’re considering, simply divide the cost of the cash ticket minus taxes and fees ($5.60 per one-way domestic flight on United) by the cost of the award ticket in miles to get a cent-per-mile value.

For example, if a ticket costs $250 or 15,000 miles plus $5.60 in taxes and fees, the math would be (250 - 5.60) / 15,000 = .016. Multiply that by 100 to get 1.6 cents per mile, which is above our average value by .04 cents. That indicates that this award ticket is a good deal.

Best United flights to Vegas

Get to know the general United MileagePlus experience in Vegas, then look to these airports for booking flights from the United website or app.

1. LAX to Las Vegas for 5K miles

Los Angeles and Las Vegas aren’t far from one another, so it makes sense that this route would offer some of the cheapest award flights. You’re likely to find economy flights for the low price of 5,000 miles and First Everyday Award flights at around 25,000 miles.

Flying to Las Vegas from Los Angeles with United Airlines is also fairly inexpensive from a cash standpoint, meaning miles aren’t worth quite as much on most flights. A $39 flight costs 5,000 miles, which comes out to 0.8 cent per mile, far less than United’s mile valuation. Check the math before you book and only redeem miles for more expensive flights if you want to get the most value.

2. Newark to Las Vegas for 9.2K miles

Newark, New Jersey, just outside of New York City, is one of United’s hubs. Because of this, you’re able to get a good deal on award tickets from the NYC area. While there aren’t a ton of these low-mileage award flights on the calendar, you can make the trip to Las Vegas for as few as 9,200 miles.

The cash cost of the same economy flight is around $114, which means miles are worth nearly 1.2 cents each and are in line with the NerdWallet valuation.

3. San Francisco to Las Vegas for 5K miles

This sub-2-hour flight is a cheap one, both in cash and in miles. An economy seat could cost around $69 at the low end, or 5,000 miles, meaning miles are worth 1.4 cents apiece. It’s worth it to do the math before you book to make sure you’re actually getting a cheap flight to Vegas.

4. Chicago-O'Hare to Las Vegas for 7.8K miles

Chicago’s O’Hare is United’s main hub, so it makes sense that flights to and from this airport would be plentiful and often inexpensive, and that includes travel to Las Vegas. For as little as 7,800 miles, you can book an economy flight.

The same flight in cash may cost $59 or $99, resulting in a value of 0.8 cent or 1.3 cents per mile. If you’re going to cash in your miles, they’ll be more valuable on high-priced flights.

5. Denver to Las Vegas for 6.9K miles

Another short-haul flight, travel from Denver to Las Vegas on United can be quite affordable. Some economy tickets cost as little as $89 or 6,900 MileagePlus miles. That gives miles for those flights a value of 1.3 cents per mile, which is above the valuation.

6. Houston to Las Vegas for 9.7K miles

Flying from Texas? Good deals can certainly be had on travel between Houston-Intercontinental and Las Vegas. Many award flights are 9,700 miles or $119, making for a fairly steady valuation of 1.2 cent per mile.
