Domestic vacations and car travel offer more spontaneity for unplanned trips. However, when it comes to air travel, booking your tickets in advance is usually the better idea. Here are a number of reasons for you to consider booking flights in advance rather than last-minute.

1. There Are More Flight Options To Choose From

You are open to more travel options, including flight times, price ranges and airlines to choose from. Even if you fly with one of the best airlines in the world, a positive flying experience depends on more than just the airline.

Factors such as departure time, seating options and other details can affect your travel experience. It is always better to have various options to choose from rather than being stuck on a late flight and feeling tired on the first day of the trip, especially if you are prone to insomnia.

2. Ease of Mind

Plan your trip with a calm mindset rather than being in an uncomfortable, rushed mode to compete for last-minute tickets. If you have an important event to attend, book in advance and stay worry-free instead of stressing until the day of your flight.

3. Better Travel Route Plan And Explore Every Option

If you are considering different destinations for your next trip, thanks to the time in your hand, you can better prepare with more time spent in researching destinations and designing different itineraries.

Finding the best flight deals is a rewarding experience for every traveller. Even though airfares tend to fluctuate, there are a few rules of thumb that you can follow to avoid costly tickets. Understanding what influences the airline pricing system is an important step.

For example, every seasoned traveller knows that the most influential factor when it comes to airfares is demand. Overall, factors that influence airfares are demand, flight route, flight time, special events and booking window.

CABINZERO's Tips: If you find a fair deal, consider booking to keep that ticket, as many airlines allow passengers to cancel without paying a penalty within 24 hours.

Avoid Peak Season Travel

Try to travel outside of high-demand periods. Most airlines calculate their costs and sell the same seat option at different prices, depending on different booking times.

Avoid flying during high-season periods such as summertime and holidays. Or when there is a big event such as a festival or sporting event in your chosen destinations.

By using a variable pricing strategy that is based on demand and supply, airlines can maximise their revenue. Travel during holiday time or booking a flight to popular destinations tend to have higher ticket prices. This is due to high demand, thus, a significant increase in airfares.

Opt For In-demand Flight Routes

If you can pick any destination to travel to, try to pick a flight route that is in high demand or too exclusive. When a route have many flight offerings from different airlines, the airfares tend to be lower. In contrast, destinations with fewer commercial flights or serviced by only one airline may have higher airfares due to limited competition.

Book Airfare Directly Through the Airline

Consider booking directly with the airline via their website or hotline. Sometimes, airlines offer a better price than other booking apps. It is always worth checking all the options before you finalise your ticket payment.

CABINZERO’s Tips: If you are a frequent air traveller, you can use your flyer miles and save even more when booking directly with your airline. If you are lucky, you can even upgrade to first class for free.

Choosing flights based on destinations and travel dates before checking airfares. By choosing to travel on days with low-cost tickets to low-demand destinations in low-season time, you can save more on tickets and spend more on the travel experience.

Relying on last-minute deals instead of monitoring flights early. If you have a fixed destination in mind and a few travel dates to choose from, monitor airfares early and book when the price drops. Last-minute flights can have soaring prices for various reasons. For instance, rising demand for last-minute flights for business or personal reasons and peak travel periods are reasons that can make airfares increase.

Overlooking the fine print or falling for advertisements without checking the policies applied. Many low-cost airlines offer cheaper fares in exchange for losing access to free carry-on allowances. Be extra careful and read the fine print whenever you finalise a booking. Hidden costs can also be avoided if you check all the policies carefully.


1. Which are the best websites for flight booking?

Flight search engines such as Google Flights, Skyscanner, Momondo, Hopper, Kayak, Expedia and Orbitz are great places to compare prices from different airlines to finalise your booking. There is no ultimate place that can offer the lowest airfares on a flight every single time. Compare different flight rates and plan in advance for the best possible rates.

2. How to book flights?

Each traveller has different preferences when it comes to booking, from accommodations to flight tickets. If you have time to research and compare different travel options, such as cheap travel dates in different destinations, you can book flights via flight booking websites and travel apps. If you are more traditional or do not have much time at hand, you ask travel agencies or contact directly to your preferred airline to get flight tickets.

3. Are flights cheaper close to departure dates?

There are many factors that can affect airfares. Booking closer to departure dates or replying on last-minute flights do not guarantee the lowest price tickets for travellers. Stay on top of price trends for your selected flight routes and monitor how prices fluctuate to find the best airfares for your upcoming trips. 

4. When to book flights with the best airfares?

For domestic trips, you can monitor the prices and book from one to three months in advance for a good deal. For international trips, you should book in advance three to eight months before your preferred travel dates. If you must travel in high-demand periods, start monitoring airfares early.
