Cebu Pacific recently had another P1 seat sale over the weekend. 

Question :  How much does one really save on a P1 seat sale?

Answer :  Anywhere in the vicinity of P 287 pesos per trip or P 574 round trip (Bacolod-Manila-Bacolod).

The taxes pinned on the supposed one peso fare is P 2,852.32 (round trip) .  So on this sale, a round trip ticket to Sugarlandia turns out to be P 2,854.32  .

Just something to think of as the large majority of "Juans" are sucked into Cebu Pacific's ingenious marketing ploys
