In recent years, global travel has been transformed by low-cost carriers, also known as budget airlines. These companies have made flying more accessible by focusing on a "no-frills" model. This means they offer very basic services, stripping away extras like free meals to keep the initial ticket price as low as possible. The goal is simple: get you from one place to another safely and cheaply.

This trend is very noticeable in Vietnam. Airlines like Vietjet Air have created a boom in domestic and regional tourism, especially among young people and families. Suddenly, weekend trips to cities like Da Nang or beach holidays in Phu Quoc are much more affordable. This has opened up new travel opportunities for a generation that previously found flying too expensive for regular vacations.

But how do these airlines profit with such low fares? The secret is charging extra for things traditional airlines often include. This includes fees for checked baggage, choosing your seat, and even printing a boarding pass at the airport. Furthermore, to save on costs, some budget carriers use smaller, less convenient airports located further from the city center.

Ultimately, budget airlines are a fantastic tool for seeing the world, but they require you to be a savvy consumer. The advertised price is just the starting point. To avoid surprises, it's crucial to read all the rules, pack light to avoid baggage fees, and compare the total cost—not just the ticket price—before you decide. Smart planning is key to benefiting from this travel revolution.
