operations resumed on June 1, 2020 after a three-month lockdown that halted the operations of public transport. The use of face masks (and later, face shields) became mandatory since the resumption of operations in June 2020. The use of face shields later became no longer mandatory in public transport in November 2021, except when an area is under the two highest levels of the alert level system. Social distancing measures were also implemented. Since March 1, 2022, all railway lines are operating at a full capacity due to the de-escalation of Metro Manila to the lowest of the five levels of the alert level system. In addition, talking with other passengers and answering phone calls in trains has been prohibited in the system. The policy has also been implemented in all railway lines and forms of public transport. The trains are regularly being disinfected when the train arrives at a terminus. It takes three to five minutes for a train to be disinfected. In addition, Line 1 trains are installed with UVC disinfection and HEPA filter systems in air-conditioning units to remove pathogens and keep indoor air clean.

Passengers using single journey cards are charged ₱15 for travelling ; ₱20 for ; or ₱30 for distances more than . Stored value (Beep) cards are also charged depending on the distance travelled in kilometers, but on a more finely graduated basis. Beep card users are charged ₱1 for every kilometer travelled, plus the ₱11 boarding charge. The Line 2 uses the same fare matrix with the Line 1, but passengers are charged ₱25 for travelling a distance more than . Ticketing Before 2001, passengers on Line 1 would purchase a token to enter the station. Subsequent upgrades
