MANILA – Grab Philippines is investigating reports that some GrabUnlimited subscribers have been charged higher fares compared to regular users.

In a statement on Tuesday, the ridesharing and delivery company said its prices are generated in real time, based on factors such as supply and demand, distance, estimated travel time, route conditions, and driver or delivery partner availability.

“Because these factors shift continuously—sometimes within seconds—two transactions for what appears to be the same route or order, initiated even moments apart, may reflect different prices. This is also why prices may vary between devices, sessions, or times of day,” Grab said.

The company added that its pricing system applies the same methodology to every user and does not charge different base prices based on subscription status or frequency of use.

“Promotions, vouchers, and subscription benefits such as discounts are applied on top of the same base price that any user would see at that moment,” Grab said.

Despite this, Grab acknowledged the allegations of fare discrepancies and has launched an internal review of specific cases, along with a broader review of its pricing system.

“[This is] to confirm that they are operating exactly as designed and as we have described. Should this review surface anything that requires correction, we will act on it,” the company said.

The claims surfaced after several netizens posted examples of fare differences on social media. On March 29, one user showed she was charged PHP216 for a trip under GrabUnlimited, while her mother’s regular account was charged PHP192 for the same route. Another post on March 27 showed a user being charged PHP438 under her GrabUnlimited and GrabUnlimited Car subscriptions, while her son’s regular account paid PHP360 for the identical trip.
