Update
Hi everyone,
Thank you all for your comments regarding our display of MileagePlus earning information.
We are aware that there are some rare instances, where international surcharge is being excluding from the display of award miles and PQD when viewing your upcoming reservation on United.com. We expect to have the earnings display corrected shortly. Please rest assured that the final earnings reflected in your Account summary once you have flown will include the surcharge.
