The Yellow Line was the second of BART's five rapid transit lines to open. Service from {{bart|Concord}} to {{bart|MacArthur}} began on May 21, 1973. The line was extended to {{bart|Daly City}} when the Transbay Tube opened on September 16, 1974. The {{bart|North Concord/Martinez}}, {{bart|Colma}}, and {{bart|Pittsburg/Bay Point}} stations were added in 1995–1996.{{BART History}}

Until 2015, rush hour service included trains that short turned at Concord; these trains originated at {{bart|Montgomery Street}} during the morning peak and returned to 24th Street Mission during the evening peak. On April 1, 2015, BART fully opened the Central Contra Costa Crossover, a pair of crossover tracks south of Pleasant Hill/Contra Costa Centre station that allow trains to terminate there.{{cite press release |url=https://www.bart.gov/news/articles/2015/news20150401 |title=BART opens Contra Costa Crossover |publisher=San Francisco Bay Area Rapid Transit District |date=April 1, 2015}} On September 14, 2015, the Concord short turns were cut to Pleasant Hill to allow for increased frequency. Reverse peak "Pleasant Hill Limited" trains bypassed Rockridge, Orinda, Lafayette, and Walnut Creek stations eastbound in the morning peak, and Lafayette and Orinda westbound in the evening.{{cite press release |url = https://www.bart.gov/news/articles/2015/news20150910 |title = BART schedule change aims to provide some crowding relief |publisher = San Francisco Bay Area Rapid Transit District |date = September 10, 2015 }} The short turn trains were re-extended to Concord on February 10, 2020.{{cite press release |url = https://www.bart.gov/news/articles/2020/news20200131-0 |title=BART schedule change begins February 10, 2020 |publisher=San Francisco Bay Area Rapid Transit District |date=January 31, 2020}} The extra commute trains were eliminated effective March 19, 2020, due to ridership decreases caused by the COVID-19 pandemic.{{cite press release |url=https://www.bart.gov/news/articles/2020/news20200318 |title=Yellow line extra commute trains cancelled during low ridership |date=March 18, 2020 |publisher=San Francisco Bay Area Rapid Transit District}}

In March 2016, mysterious electrical surges caused several cars to be taken out of service on the tracks north of North Concord/Martinez station. On March 16, 2016, BART halted service to Pittsburg/Bay Point station and established a bus bridge between North Concord and Pittsburg/Bay Point.{{cite news |last1 = Gafni |first1 = Matthias |title = BART nearing full restoration of service |url = http://www.contracostatimes.com/breaking-news/ci_29700468/bart-working-resume-full-service |access-date = March 31, 2016 |work = Contra Costa Times |date = March 29, 2016 }} Limited service to Pittsburg/Bay Point resumed on March 21Steve Rubenstein, "BART restores limited commute service to Pittsburg/Bay Point Station."

When the SFO/Millbrae extension opened on June 22, 2003, BART extended the Yellow Line to Millbrae but bypassed San Francisco International Airport station (SFO). BART rerouted this line to SFO in place of the Blue Line on February 9, 2004, with service extended to Millbrae outside of weekday peak hours.

San Mateo County is not a member of the San Francisco Bay Area Rapid Transit District, so SamTrans funded the county's BART service. When the extension's lower-than-expected ridership caused SamTrans to accrue deficits, BART agreed to SamTrans' request to operate only the Blue Line south of Daly City effective September 12, 2005.

SamTrans and BART reached an agreement in February 2007 in which SamTrans would transfer control and financial responsibility of the SFO/Millbrae extension to BART, in return for BART receiving additional fixed funding from SamTrans and other sources.{{cite web |archive-url=https://web.archive.org/web/20090512072440/http://apps.mtc.ca.gov/meeting_packet_documents/agenda_807/3d_MTC-BART-SamTrans_Settlement_Agreement.pdf |archive-date=May 12, 2009 |url=http://apps.mtc.ca.gov/meeting_packet_documents/agenda_807/3d_MTC-BART-SamTrans_Settlement_Agreement.pdf |title=BART-SFO Settlement Agreement and Release of Claims |publisher=Metropolitan Transportation Commission |date=February 14, 2007}} In January 2008, BART re-extended the line to SFO at all times, and in September 2009, trains were further extended to Millbrae on evenings and weekends.

Beginning on February 10, 2020, the Yellow Line again terminated at SFO at all times, and service from SFO to Millbrae was once again provided by the Purple Line.{{cite web |url=https://www.bart.gov/sites/default/files/docs/February%202020%20BART%20Public%20Timetable%20Weekday%20Final%20all%20Lines.pdf |title=Weekday Schedule as of February 20, 2020 |publisher=San Francisco Bay Area Rapid Transit District}} Yellow and Purple line trains were interlined on Sundays, with no transfer required at SFO.{{cite press release |url=https://www.bart.gov/news/articles/2020/news20200131-0 |title=BART schedule change begins February 10, 2020 |date=January 31, 2020 |publisher=San Francisco Bay Area Rapid Transit District}} Beginning on March 22, 2021, the Yellow and Purple lines were interlined on both Saturdays and Sundays.{{cite press release |url=https://www.bart.gov/news/articles/2021/news20210316 |title=BART schedule change begins March 22, 2021 |date=March 16, 2021 |publisher=San Francisco Bay Area Rapid Transit District}} On August 2, 2021, the Purple Line was eliminated as a separate service, with the Yellow Line extended to Millbrae on evenings and Sundays when the Red Line was not operating.

On January 13, 2025, a shuttle train began operating between SFO and Millbrae between 9 pm and midnight due to the installation of Communications Based Train Control equipment near Millbrae. It is signed as part of the Yellow Line.{{cite press release |url=https://www.bart.gov/news/articles/2024/news20241216-0 |title=BART’s schedule will change on January 13, 2025, to launch construction of a modern train control system |date=December 16, 2024 |publisher=San Francisco Bay Area Rapid Transit District}}

Trains and tracks for the portion of the Yellow Line between Antioch and Pittsburg/Bay Point are incompatible with those of the main BART rapid transit system, making it impossible for trains to move between the two systems;{{cite magazine |title = Stadler awarded eBART train contract |url = http://www.railwaygazette.com/news/passenger/single-view/view/stadler-awarded-ebart-train-contract.html |magazine = Railway Gazette |publisher = DVV Media UK |date = April 28, 2014 |access-date = November 18, 2015 |archive-date = November 20, 2015 |archive-url = https://web.archive.org/web/20151120024335/http://www.railwaygazette.com/news/passenger/single-view/view/stadler-awarded-ebart-train-contract.html |url-status = dead }} instead, passengers transfer via a cross platform interchange at an auxiliary BART stop to the east of Pittsburg/Bay Point{{snd}}the BART to Antioch platform is accessible only via an intra-station ride from the main station to this auxiliary stop.
