If you are planning to travel next year, you will want to plan a travel itinerary to avoid missed flights, air fares and travel cancellations.

If you do not, you could face a hefty penalty on your airfare.

If air travel is one of your main expenses, it is crucial that you do the research before making your flight plans.

Below is an infographic that outlines some key tips to avoid the disappointment of missed flights and air fares, and how to avoid these pitfalls.

If a flight is cancelled due to weather, delays, or other unforeseen circumstances, you can contact your airline for assistance.

Some airlines have more stringent policies for cancellations, but it is important to check with your airline and check with them before you travel to ensure you have the right travel documents, so you do have the peace of mind to make the most of your flight and travel.

If your flight has already been cancelled, it can be a good idea to book another ticket if you have already made arrangements with the airline, to avoid having to reschedule or cancel the flight.

Here are some of the important things to consider when making travel plans, and when making a booking.

Where to book a flight If you need to travel more than a week before your flight, consider booking a round-trip flight with a higher ticket price, rather than a cheaper round-trips option.

You can find out more about booking round-tickets here.

For example, if you want to travel from Sydney to Melbourne, you may be able to book from Sydney, via Melbourne Airport, for $250 round trip.

If, however, you want a round trip from Sydney Airport to Brisbane, then you would need to book the same round- trip from Brisbane Airport, via Sydney Airport, at $300 round trip, or you would pay more.

Round-trip tickets can only be booked from Sydney and not from Brisbane.

If possible, book your round-to-round ticket from Sydney airport if possible, but if not, make sure you are booking round tickets from Brisbane airport, as it is the only option for round-ticket travel from Brisbane to Melbourne.

Round trip tickets must be booked online.

You must check the booking confirmation and pay the applicable fees, including air fare, before you can travel.

Air fares are typically less expensive than round-backwards tickets.

You may also be able a cheaper airfare option from Brisbane than Sydney.

For round-based travel, check with the airlines about their air fare policies.

If it is a roundtrip, check the terms and conditions of the trip.

Some flights may be longer than others, but there are usually fewer restrictions than a round.

For instance, flights from Sydney or Brisbane may require you to pay a higher air fare than a return trip from Melbourne Airport.

Check with the relevant airline before making a round travel decision.

If there is a delay, or a flight does not arrive on time, it may be a valid reason to cancel the trip and rebook the flight with an alternative destination, but that may not be the same as rescheduling the flight or cancelling the ticket.

You might also be required to pay additional fees, such as an extra baggage fee.

If the delay is a result of a weather-related emergency, you should contact your nearest police station or the airport to arrange for a local emergency response team.

If weather delays are a concern, contact your travel agent, who can arrange for your flight to arrive on schedule.

Travelers should always check with their travel agent about the conditions of travel before making any booking decisions.

The most important thing to remember when making your booking is that it is your responsibility to check the conditions before booking your travel, and if there are any problems, the airline should be able or willing to help.
