The monorail takes approximately two minutes to travel between the Seattle Center and Westlake Center terminals, which are located {{convert|0.9|mi|km}} apart. Trains depart from each terminal approximately every 10 minutes, with a single train running continuously. The service has two seasonal schedules, with trains in the autumn and winter (September to May) operating for 13–14 hours per day from Monday to Saturday, ending at 11:00 p.m. on Fridays and Saturdays, and 12 hours on Sundays, ending at 9:00 p.m. The summer schedule is in use from May to September and has weekday trains operating for 16 hours and weekend trains for 15 hours, with service ending at 11:00 p.m. every day.{{cite web |title=Tickets, Hours & Information |url=https://www.seattlemonorail.com/information/ |work=Seattle Center Monorail |url-status=dead |archive-url=https://web.archive.org/web/20190516215455/https://www.seattlemonorail.com/information/ |archive-date=May 16, 2019 |access-date=February 28, 2020}} Monorail service is typically reduced on national holidays and closed entirely on Thanksgiving Day and Christmas.{{cite web |date=October 10, 2012 |title=Seattle Monorail Holiday Schedule |url=https://www.seattlemonorail.com/events-and-news/seattle-monorail-holiday-schedule/ |work=Seattle Center Monorail |access-date=February 28, 2020 |archive-date=September 25, 2019 |archive-url=https://web.archive.org/web/20190925040823/https://www.seattlemonorail.com/events-and-news/seattle-monorail-holiday-schedule/ |url-status=dead}} During special events at the Seattle Center and Climate Pledge Arena, operating hours are extended and train frequencies are increased to every four minutes by using both trains in the fleet.{{cite web |date=September 24, 2024 |title=Extended Hours of Operation 2024 |url=https://www.seattlemonorail.com/extended-hours-of-operation/ |work=Seattle Center Monorail |accessdate=September 26, 2024}}

Since the opening of Climate Pledge Arena, monorail ridership has recovered to its pre-pandemic levels with more use outside of the peak tourist season. On June 29, 2023, a set of 16 monorail columns on 5th Avenue between Olive Way and Vine Street were painted with portraits of Major League Baseball (MLB) players and local sports fans. The murals by artist Brady Black were commissioned by tourism agency Visit Seattle to celebrate the 2023 MLB All-Star Game, which Seattle hosted in July. Black and several volunteers painted the portraits onto mural cloth and transferred them to vinyl to be installed by crane on the columns.{{cite news |last=Grossman |first=Sophie |date=July 3, 2023 |title=The story behind Seattle monorail pillars' MLB All-Star murals |url=https://www.seattletimes.com/entertainment/visual-arts/the-story-behind-seattle-monorail-pillars-mlb-all-star-murals/ |work=The Seattle Times |accessdate=July 5, 2023}} An additional 14 columns were decorated in 2024 with linocut artwork from local students that depict local events and attractions in Seattle.{{cite web |date=May 24, 2024 |title=Monorail Column Mural Project |url=https://www.seattlemonorail.com/monorail-murals/ |work=Seattle Center Monorail |accessdate=June 27, 2024}}

The monorail has been the subject of several expansion proposals, with the primary goal of expanding it into a citywide rapid transit system. In 1961, businessman Ben B. Ehrlichman proposed that the then-unfinished monorail be extended north to Alderwood Manor or Mountlake Terrace and south towards Seattle–Tacoma International Airport, Kent, and Renton. The initial system would have cost $60 million (${{Format price|{{Inflation|US-GDP|60000000|1961}}}} in {{Inflation-year|US-GDP}} dollars),{{inflation-fn|US-GDP}} while a second line serving the Eastside region would be built separately using a new floating bridge. Former Seattle Transit System manager Marmion D. Mills proposed his own monorail system in 1963 that would connect Seattle to Mountlake Terrace, Kent and the airport. Mills argued that a conventional subway system would be too expensive for Seattle and that the other alternative would be an expanded freeway network.{{cite news |last=Miletich |first=Matt |date=February 24, 1963 |title=Seattle's Dreams of a Monorail System |pages=12–13 |work=Charmed Life Magazine, The Seattle Times}}

The Regional Transit Authority (later Sound Transit) was formed in 1993 to create a regional light rail plan that was ratified by voters in November 1996. Taxi driver Dick Falkenbury conceived a separate proposal in 1996 to build a citywide monorail system and submitted a ballot initiative after a signature-gathering campaign.{{cite news |last=McDermott |first=Terry |date=July 4, 1996 |title=A gridlocked city could take the monorail to new lengths |page=B1 |work=Seattle Post-Intelligencer}} Falkenbury's proposal envisioned an X-shaped system with service from Downtown Seattle to Ballard, Lake City, the Rainier Valley, and West Seattle, which would cost $850 million to construct (${{Format price|{{Inflation|US-GDP|850000000|1996}}}} in {{Inflation-year|US-GDP}} dollars).{{inflation-fn|US-GDP}}{{cite news |last=Godden |first=Jean |date=November 8, 1996 |title=Monorail X plan is still RTA plan B |page=B1 |work=The Seattle Times}}{{cite news |last=Modie |first=Neil |date=November 14, 1996 |title=Monorail extension up for vote |page=B1 |work=Seattle Post-Intelligencer}} 53 percent of voters approved the monorail plan, named Initiative 41, in a general election on November 4, 1997, creating the Elevated Transportation Company (ETC) to seek financing.{{cite news |last=Crowley |first=Walt |date=April 14, 2003 |title=Seattle voters approve Initiative 41 Monorail plan on November 4, 1997. |url=https://www.historylink.org/File/2525 |work=HistoryLink |access-date=March 3, 2020 |archive-date=December 18, 2019 |archive-url=https://web.archive.org/web/20191218052701/https://www.historylink.org/File/2525 |url-status=live }}
