Keep your plans flexible
Many recommend booking a flight at least three or four months ahead of time. It’s certainly cheaper than booking the day before – stats suggest that you could pay more than two and a half times for a ticket to popular regional destinations like Bali and Bangkok. But whatever it is, make sure to keep your plans flexible. Instead of booking a fixed ticket with stringent dates, top up a little extra for a flexi ticket. For instance, Singapore Airlines lets you change your travel date or destination, and even offers the option of getting a full refund.
