買機票是否越早越便宜？

The answer is no.

Airlines ticket price is driven by supply and demand, as well as competition.

The best way to find a cheap ticket:

1. Find out about the average price (You can do so by talking to travel agency staffs).

2. Periodically checking the inventory (seat availability) as well as promotion.

3. When the price drops to certain level, book it.

#3 is the most difficult because no one (even the airlines) knows what can be the bottom line price is. But for example. If the average cost of the ticket is HKD$8,000 and right now the price is about HKD$5,500 for direct non-stop, you should think about is it a price that you can afford and buy.

There is no easy way to score a cheap ticket.

It is cheap when you are buying a ticket now and traveling really soon. But it is not the cheapest. So you have to evaluate yourself.

yes, you can say so.

but how early is a question. normally, you like to get a cheaper price, choice of good seat. you need to oder the ticket 6 weeks before your trip. anytime within 4 weeks the price of same flight will be different day by day.------ still not much different, about $20 to $50. until the lastest week.

but the cheapest plane ticket you can get is from the choice of airline and flight schedule. day or night; weekday or weekend flight; holiday season.....etc. those factors you also need to be consider.

並非有這一回事機票分旺季與賽淡季之分
