First, always keep in mind that in booking for promos, you should spend time in lurking for promos 2 to 3 months before your flight. Almost everybody complains " I am too late to book!", Booking is over! Fast approaching cheap flights are so hard to find!
Second, book in small group.
There are those who book for 5 person or more at a time. Of course, there are circumstances that you cannot break the group especially if there are children. But if you can manage to break your group into smaller ones, there's a big chance that you can get tickets during a promo. Here's the reason why.
When you enter five or more persons in the search query, the system will look for a specific promo flight with five or more vacant seats. What if there's only four left? The search will return "zero" result. Which is better? Four promo fares plus one regular fare or five regular fares?
Third, travel on non busy days or times.
Avoid flying on Fridays or Mondays, they are considered to be busy days because most people tend to travel on those days. Because of high demand, there are usually no promos given on those days.
Also, if you can manage to fly late or early in a day, please do so because cheap fares are usually offered on those times.
The principle is, fly when you think there's less people who likes to fly.
Fourth, Have a Credit Card, Debit Card, or an ATM card that supports online purchasing.
Promo fares are best purchased through the internet. It is both fast and convenient. Some promos such as "Piso Fare" can only be booked online.
If you are not sure whether your ATM Card is capable of booking online, contact your card provider.
