When to Travel

Typically, you can find flight deals on domestic airline tickets anywhere between one and three months before your departure date. However, holidays and busy travel weekends can affect prices. If you do plan to travel during the busy times of year, the best way to save money is by taking advantage of Allegiant’s affordable flights.

On average, the cheapest day of the week to fly to Knoxville with Allegiant is Thursday. Traveling during the week can mean less crowded airports and cheaper flights. One of the simplest ways to ensure the cheapest flight deals once you have your travel dates set, is to book a round-trip flight. Airlines typically offer discounts when both legs of the trip are booked at the same time versus booking two one-way flights, and Allegiant is no exception. The airline offers exclusive flight deals to Knoxville that are only available when booking round-trip flights, saving time and effort in the ticket buying process and guaranteeing you get the cheapest round-trip tickets available. If possible, you should try to avoid booking your flight less than a month before your departure date to save even more money. Last-minute flight prices in the days leading up to departure tend to spike dramatically.

Best Time to Visit Knoxville

On average, the cheapest months to visit Tennessee are May and June. If traveling in July and August, you can find the best prices when you book flights through Allegiant. Summer tourism is at its peak during these months, so there will be plenty to see and do. Just be prepared for the warm Tennessee climate and possibility for larger crowds. Tennessee is a sight to see in the autumn with the beautiful fall foliage, but if you visit during college football season, be prepared for higher hotel prices. If you visit during this time, you could still save money by taking advantage of cheap flights offered through Allegiant.

The Airport You Fly Into Matters

Taking advantage of direct flights when flying into Knoxville can be a time-saver. Not all airports and airlines offer nonstop flights between St. Louis and Knoxville, and layovers can cause you to waste more time traveling rather than vacationing. Once you have your travel timeframe decided, compare different flights from different airports to find one that works best with your budget. Your best bet would be to look at the flights offered between BLV and TYS.

Expand Your Lodging Accommodations

Where you stay when traveling can put a huge dent in your budget. Generally, downtown and high-density urban area lodgings near Market Square and city center are more expensive. If you’re looking to save money, check out hotels outside of downtown Knoxville and those located in the surrounding suburbs. Hotels are not the only accommodation you should consider, either. Sometimes, opting for a motel, bed and breakfast, Airbnb, or VRBO rental can help you save money on your trip.

Save Time and Money Flying

With an average flight time of just one hour, flying into Knoxville saves you time and money when compared to driving. A typical car trip from St. Louis to Knoxville takes about seven hours, cutting into valuable time you could be spent vacationing. Flying into Knoxville’s McGhee Tyson Airport from MidAmerica St. Louis Airport saves time, while also helping you saving money on gas and car maintenance.

Check in Online for Free

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 for your flight online. Allegiant offers free check-in through its mobile app and online services. Check-in opens online 24 hours before the flight and is available until 45 minutes before departure. This option allows you to receive your seat information and access your boarding pass all online for free. 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, offers increased leg room, a complimentary beverage, snack and other perks, is offered on most Allegiant flights, for a nominal fee.

Compare Car Rental Services

Like airports and airfare, not all car rental services are created equal. To save money and find the best fit for you, it’s best to compare different companies to find a car that will work for you and your budget. If you know your travel dates ahead of time, renting a car before you arrive to Knoxville can help you save money.
