( CNN ) -- UPS on Friday finished delivering its backlog of holiday packages , company spokeswoman Natalie Godwin told CNN . The company earlier this week said that the volume of packages in its system exceeded its capacity , causing delays . The delays meant that some packages were not delivered before Christmas , despite promises by some retailers . UPS did not provide numbers , but the spokeswoman said the backlog was cleared Friday . `` Yes , the holiday packages have been delivered , '' Godwin said . The company considered Christmas Day deliveries as an emergency measure , but `` after much thought and consideration '' decided not to ask drivers to work on the holiday . The delays angered many customers , who took to social media to vent their frustrations . The company said that previous severe weather in the Dallas area had already created a backlog , and the holiday volume proved too much . FedEx was late with some deliveries as well , but called them `` isolated incidents . '' On Saturday , FedEx reported that `` any isolated issues are resolved . '' The U.S . Postal Service did not comment on whether it experienced any similar delays . CNN 's Josh Levs contributed to this report .
