Update: Latest PAL and PAL Express Monday Madness can be viewed at this Airline Promos Page . Remember the old PAL Midnight Sale? For those who don't, it is a promotion of Philippine Airlines wherein they offer cheap fares to certain destinations and travel dates every Sunday midnight until 6 in the morning. I still remember the first one back in 2011. PAL's website was inaccessible for almost three hours due to the flood of internet traffic to their servers. Many were irritated, even angered by the unprepared airline company. Slowly though, the succeeding midnight sales becomes more stable.
