Methodology: learn how we calculate these charts
The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Baltimore to San Francisco cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.
Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.
Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.
The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.
Frequently Asked Questions
Everything you need to know about flying from Baltimore to San Francisco.
What is the typical flight duration from Baltimore to San Francisco?
The flight from Baltimore to San Francisco is about 2,450 miles. Nonstop flights typically take 5 hours 50 minutes outbound, while the return to Baltimore is shorter at 5 hours 19 minutes due to prevailing winds.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.
Are there any direct flights from Baltimore to San Francisco?
Yes, there are direct non-stop flights from Baltimore (BWI) to San Francisco (SFO), currently flown by United Airlines and Southwest Airlines. United operates 12 weekly flights with daily departures at 6:38 AM and 6:59 PM, while Southwest runs 7 weekly flights with daily departures at 12:45 PM and 2:50 PM. Both carriers fly this route every day of the week.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.
What are the ground transportation options in San Francisco?
San Francisco International Airport sits about 13 miles south of downtown, and BART rapid rail is the fastest and most-used option, whisking you to the city center in roughly 30 minutes for about $10–$17 one-way. Rideshare services like Uber and Lyft, along with taxis, offer door-to-door convenience, while shared shuttles and SamTrans public buses serve budget travelers. Rental cars are available at a consolidated center connected by the free AirTrain, and autonomous Waymo rides are also an option for select passengers.

When is the cheapest time to fly from Baltimore to San Francisco?
Fares from Baltimore to San Francisco are lowest in late January, around $333. February is the cheapest month overall, averaging $342, followed by January ($346) and September ($364). December is the most expensive month at about $432, and fares peak in late December at about $467. The yearly average is $383. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.
How far in advance should I book tickets from Baltimore to San Francisco?
Book about 7 weeks before departure for the best fares from Baltimore to San Francisco, around $308. Booking in the final days before the flight costs about $379, $71 more. Booking six months ahead runs about $416. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.
Are overnight (red‑eye) flights available from Baltimore to San Francisco?
There are no nonstop red-eyes from Baltimore to San Francisco, but connecting overnight itineraries are available, with the long red-eye leg typically departing in the 9:30–10:50 PM window and landing just after midnight. Southwest connects through Chicago Midway (departs 9:25 PM, arrives 12:10 AM), American connects through Dallas–Fort Worth (departs 10:50 PM, arrives 12:44 AM) and Chicago O'Hare (departs 9:31 PM, arrives 12:30 AM), and United connects through Chicago O'Hare (departs 9:40 PM, arrives 12:30 AM). Each of these lands in the early hours after midnight.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
