Should I use a VPN to find cheaper flights?

In Asia, it rarely makes a difference. Prices are usually standardized by region. Focus on booking in the local currency if your bank doesn't charge foreign transaction fees.

Is it better to book round-trip or one-way?

Book one-way tickets. Regional budget airlines rarely offer discounts for round-trip bookings, and you will have more flexibility to change your route if you decide to travel by bus or train instead.

Finding Cheap Flights Around Asia

Use budget-specific search engines like Skyscanner and Trip.com, and prioritize regional low-cost carriers like AirAsia, VietJet, and Scoot. Book your flights 3 to 6 weeks in advance to secure the lowest fares on these short-haul routes.

Use the right search engines. Avoid legacy airline sites. Use Skyscanner or Trip.com, as they aggregate regional low-cost carriers (LCCs) that major global platforms often miss. Always select the 'Whole Month' view to identify the cheapest departure days.
Master the regional budget airlines. Learn which airlines dominate specific regions. Use AirAsia for Southeast Asia, VietJet for Vietnam, Scoot for Singapore/Australia, and Peach or Jetstar Japan for domestic Japanese travel. Go directly to their sites if you see a flight on a comparison engine to ensure you aren't paying a third-party markup.
Check secondary airports. Major cities often have two airports. Check fares for both. For example, in Bangkok, compare Suvarnabhumi (BKK) and Don Mueang (DMK). The savings on a flight can often outweigh the cost of an extra 30 minutes in a taxi.
Travel light to avoid add-ons. Budget airlines in Asia make their profit on checked bags. Aim to travel with a 7kg carry-on. If you must check a bag, buy the baggage allowance online during initial booking; adding it at the airport counter can cost 200% more.
