Air travel has really boomed in recent times thanks to the advent of low-cost airlines. One would be hard pressed to find a country in the world that is not connected by a low-cost airline. On many routes, the low-cost carriers are the ones making a profit while the full-service airlines are running into losses. 
The domestic routes
Domestic routes are a huge favourite for low-cost airlines. The travel times are not long. The passengers are prepared to sacrifice comforts like airline food, on-board entertainment and business class services for cheaper tickets. The journeys get over quickly and both the airline and the passengers are only interested in getting from Point A to Point B as quickly and as cheaply as possible.
The regional routes
Regional routes are also a huge favourite with low-cost carriers. Many international flights within Europe are in fact served by low-cost carriers. Travel within South East Asia is also mostly done on the back of budget airlines. Once again short distances and limited travel times play a role in the success of these carriers.
On time, every time
The best low-cost carriers are those that are always on time. There is no point in travelling by flights that are delayed. Time is money and the whole point of taking the fastest mode of transport is to save both time and money. If you are travelling during your Ph.D. and feel short of time to submit your work on time, you can take help from thesis writing support services.
Good safety record
The airline should also have a good safety record. While airlines can save money on items like food and on-board entertainment, they definitely should not compromise on the safety of their fleet. There have been budget airlines with dubious safety records and they have been forced to shut shop because passengers refused to patronise them.
Use their websites
Most of the information about low-cost airlines can be found on their websites. This saves the airline a lot of money and they tend to patronise the Web a fair amount. Details like how much luggage the passengers can bring on-board the plane and when do they have to check-in are all given on the websites. Many airlines also have web check-in and this is comfortable for the passengers.
Travel light
The best way to make use of travelling by budget airlines is to travel light. Low-cost airlines charge money for each and everything. They even charge extra if the passengers want comfortable seats. Taking even a little bit of extra luggage on-board the plane results in the passengers being charged for excess baggage. So choose these airlines when you do not have to take too many suitcases and large bags.
Eat before you fly
Eating on-board budget airlines is prohibitively expensive, so plan your flights well. Take mid- morning, late afternoon and evening flights. This way you can eat your breakfast and lunch at home and then travel and reach in time at your destination for your next meal. You can even bring a sandwich with you from home for the flight.
Even though air travel is not the cheapest way to travel, it has become more affordable. It is still the fastest way to get from one city to the other. With some careful planning, passengers can save both time and money on a good budget airline.
