Our favorite airline is Cebu Pacific for it always have a promo for discounted tickets. However, the airline's planes are pretty small with only 6 seats in a row, that's 3x3 with the aisle in the middle. And the legroom is punishing if you are a tall person (I am 5 feet 4 only so it does not bother me). Fortunately, we discovered that the online booking has a seat option where you can choose a preferred seat in the plane. And since the first row has the biggest legroom, we always get that for the price of 450 pesos which is around $10. For me and my husband, that's a total of $20 for one way and another for the return flight. It is costly but sitting in the front row is very comfortable.
