When to Book

For those looking to visit Sin City on a budget, the cheapest months to fly are between March and May. Summer tourism is at its peak in July and August, conventions tend to be held in the fall, and holidays are always a hot time to visit. In the spring, the weather tends to be milder with highs between 70 and 85 degrees, with very little rainfall. If a summer visit is a must, the first weeks of August, when families are preparing to head back to school, have the cheapest flights compared to the rest of the summer.

When flying with Allegiant, the cheapest day to fly to Las Vegas is Monday.

On average, it’s most cost-effective to buy tickets for domestic flights- including Las Vegas – one to three months before traveling. If you can avoid it, try not to buy last-minute flight tickets as flight prices tend to be more expensive.

Round-trip Flights vs. One-Way Flights

If you have travel dates set, one of the best and simplest ways to ensure you land a cheap flight when traveling to Las Vegas is to book a round-trip flight. Airlines typically offer discounts when both legs of the trip are booked at the same time vs. booking two, one-way flights. Allegiant offers exclusive flight deals to Las Vegas that are only available when booking round-trip airfare, which saves you time and effort in the ticket buying process.

Check out Membership Programs

Some hotel casinos, like MGM, Caesars and Grazie, offer free loyalty and membership programs. Before you book your hotel, sign up to receive free newsletters from different casinos for a chance to receive a coupon for your stay.

Stay Downtown and Shuttle to the Strip

Another great way to save money when visiting Las Vegas is to stay off the Strip or in downtown. Many of these hotels are less expensive but remain within walking distance of popular attractions. If you do decide to stay downtown, which is a little further from the Strip, shuttles run back and forth, making traveling between the two easy and simple.

Skip the Car Rental

Unless you’re planning on taking a day trip while visiting Las Vegas, you can generally skip the car rental. Most tourist attractions in Las Vegas are located on the Strip and are easy to get to without renting a car. Some hotels will even offer a free shuttle to pick you up from the airport after your Las Vegas flight. Ride services like Uber, Lyfts and cabs are abundant in Las Vegas, so you can get anywhere you need to go. If you are planning on venturing outside of Las Vegas and feel a rental car is a must, be sure to look around and compare rental prices. Like booking plane tickets months in advance, reserving your rental car in the same fashion can help save money as prices will be more expensive closer to your travel dates. Just be sure to be mindful of any cancellation restrictions.

Save Time and Money by Checking in Online

One thing to keep in mind – Allegiant does charge a small fee for printing a boarding pass at the airport. An easy way to save some time and money is to check in online. Allegiant offers free online check-in through its mobile app and online services. It opens online 24 hours before the flight and is available until 45 minutes before departure. This option puts seat information and boarding passes right at your fingertips. Travelers can also choose their seat assignments in advance or have Allegiant assign seats to them at check in. The option to upgrade to Allegiant Extra, the airline’s premier cabin class that offers increased leg room, a complimentary beverage, snack and other perks, is offered on most Allegiant flights, for a nominal fee.
