One-way or round-trip tickets when studying abroad: cost analysis

🔄 Cập nhật lần cuối: 08/10/26

Buying a one-way or round-trip ticket when studying abroad is a question that almost every family encounters when booking tickets for the first time. Round-trip tickets are sometimes only a little more expensive than one-way tickets, but if you don't use the return trip, it's a waste. This article analyzes costs and specific situations so you can make the right choice.

Difference between one-way and round-trip tickets

• One-way ticket: only the outgoing leg. Absolute flexibility for future return trips, no worries about losing money for unused flights.
• Round-trip tickets: include both the departure and return flights in one booking. Usually has a maximum validity (commonly 12 months from departure date, depending on price conditions). The return leg must be booked on a specific date and can be changed according to ticket conditions.

What many people don't know: on some international routes, round-trip tickets can be only a small amount more expensive than one-way tickets, sometimes even equivalent. The reason is the way firms build their price schedules. On the contrary, there are companies that sell very competitive one-way tickets. There is no general rule, we must compare specifically each line and each time.

Analyze the cost of one-way or round-trip tickets to study abroad

To compare properly, don't just look at ticket prices. Let's calculate the total expected costs:

Thinking example

Suppose you are sure to return to Vietnam for the summer after 10 months. If the round-trip price is only about 30–50% higher than one-way, buying a round-trip is often more profitable than buying a return ticket during peak season. On the contrary, if you study for 3–4 years and don't know when to return, the 12-month round-trip ticket will almost certainly be wasted on the return trip. At this time, you should choose one direction.

Which type of ticket should I choose according to each situation?

• Preparatory course, short-term language course (under 12 months): consider round trip, choose ticket class to change return date.
• University 3–4 years, master's 2 years: usually choose one way, buy separate return tickets when scheduled off.
• Have plans for Tet or summer of the first year: compare round trip with flexible return date with one way plus return ticket during peak season. See Air tickets to Tet for international students.
• High school students (under 18 years old): Vacation schedules are usually fixed, round trips may be reasonable. See Book tickets for international students under 18 years old.
• Interns, contract workers: usually buy one way; The return leg is booked at the end of the contract. See return home after the labor contract.

Do I need a round-trip ticket to enter the country?

For international students with a valid student visa, countries such as the US, UK, Australia, and Canada are usually not required to have a round-trip ticket upon entry. Requiring a round-trip ticket or departure ticket usually applies to tourists, visa-free. However, regulations may vary by country and visa type. The airline can check documents at the check-in counter, so bring your admission letter and visa. See Documents needed to carry with you when flying to study abroad.

Important notes when buying round-trip tickets

1. Must fly in order: if you miss a leg, the airline usually automatically cancels the next legs. Don't buy a round trip "from abroad to Vietnam" and then skip the first leg.
2. Read carefully the conditions for changing the return date: change fee, price difference, deadline to change before flight time.
3. Ticket validity: calculated from the first flight date. Once the deadline expires and the return leg has not been flown, that leg usually loses value.
4. Baggage for the return leg may vary depending on the airline and route.
5. Refund of unused sectors: with many cheap ticket classes, the refund only includes a portion of taxes and fees.
