This weekend, a concerned Filipino, Nityalila Saulo, video-documented an instance where the guards at NAIA Terminal 3 did not allow them to get a regular taxi at the departure platform. Since the airport taxi, the yellow taxi, is queued at the arrival platform, some passengers choose to get the cheaper and regular ones.
The white taxis have a flag-down rate of 40 pesos while airport taxis charge passengers a flag-down rate of 30 pesos more on. The km-rate is also almost double as the regular ones.
If you think that it is just for MIAA to release an official memorandum on the new policy, you can sign the petition on Change.org
