The programme, as the airport counts it
SFO carries the Terminal 3 modernization at $2.8 billion inside its capital plan. The capital planning document of November 2025 records the project under Ascent Phase 1.5, in construction at 16 percent complete, with completion estimated for 2029, on data from the Design and Construction report of August 2025.
Turner Construction holds a $2.6 billion construction contract and broke ground on 5 September 2024. The two figures have two owners: the builder reports the contract, and the airport reports the programme.
Ascent Phase 1.5 carries $8.0 billion, with $3.1 billion funded and $5.0 billion unfunded.
What the scope delivers
The programme renovates 650,000 sq ft of the western half of Terminal 3 and adds 200,000 sq ft. The renovation carries a seismic retrofit, an expanded security checkpoint and new passenger amenities. The added space takes expanded food, beverage and retail concessions.
A new six-story building takes airline lounges and operational office space. The programme also covers a consolidated baggage handling system, self-bag drop, new international swing gates, a Courtyard 4 connector, replacement of building systems, and a Federal Inspection Service connector to the Customs Hall in the International Terminal.
At peak the job employs 500 to 600 workers, and the airport targets more than $173 million in contracts to Local Business Enterprises. Both lines matter to a corridor hotel selling midweek beds.
The corridor roster
Thirty hotels run free courtesy shuttles to the terminals, on a list updated 1 September 2026. Burlingame holds 11, South San Francisco 10, San Bruno seven and Millbrae two. The roster runs from the Hyatt Regency Burlingame, the Marriott Burlingame and the Hilton Burlingame to the Westin Millbrae, the Crowne Plaza Burlingame and three Sonesta properties in San Bruno and Oyster Point.
The list publishes hotel names and telephone numbers. It publishes no room count, no meeting space and no rate, so a corridor read that needs any of those has to source them property by property.
What dwell time pays for
SFO's own fact sheet counts 54,118,814 enplaned and deplaned passengers in fiscal year 2025 across 55 airlines, with 7,226 nonstop departures a week and United holding 48.7 percent of domestic and international seats combined.
That volume is the corridor's demand base. A terminal programme converts some of it into landside hours. An expanded concessions floor and a rebuilt check-in hall hold a traveller in the building longer on the departure side and on the arrival side, and the shoulder hours around a flight are the hours a near-airport room sells.
A corridor hotel within a shuttle ride also sells the hours between two flights to a group that wants a room and a boardroom in one stop.
The on-airport competitor
Grand Hyatt at SFO sits at 55 South McDonnell Road on the airport campus and reaches every terminal by AirTrain. The property holds 351 soundproof rooms including 22 suites, 11 meeting rooms and more than 14,000 sq ft of event space, with a 1,500 sq ft fitness centre, the Grand Club and a 125-space surface parking lot. Its Quail & Crane restaurant and Twin Crafts Bar serve guests, and Twin Crafts Market stays open 24 hours.
The airport's amenity page records two 2024 recognitions: the SkyTrax Passengers' Choice award for the World's Best Airport Hotels, and a Best Luxury Airport Hotel in the USA award.
That inventory sets the terms for every property on the shuttle list that competes for an early departure and a late arrival.
Meeting space sets the terms
Fourteen thousand square feet of event space on the airport campus answers the group that wants a room block and a boardroom inside one shuttle ride. That group buys space and access in one purchase.
A corridor property with its own meeting inventory competes for the same group. The published shuttle list carries no meeting-space figure for any property, so the comparison needs a property-by-property read.
Three Sonesta properties on the list trade under extended-stay and select-service flags, and that segment answers a stay length the Grand Hyatt does not market.
Where share is at risk
Read the roster against the offer. The properties most exposed are the ones whose published proposition is a shuttle and a bed, in a market where the on-airport hotel adds lounge-adjacent food, exercise, parking and a rail link to every terminal.
The properties that hold their share carry something the airport campus does not publish: a meeting room, a longer-stay apartment layout, or a brand programme a corporate account already buys.
No source in this record publishes a room count for any corridor hotel. Quantify the substitution risk property by property before acting on it.
The 2027 to 2029 sequence
Each phase changes what the airport campus offers. Fall 2027 opens the expanded western section with the added food, beverage and retail. Early 2028 opens the six-story building, which adds airline lounge capacity and office space. Early 2029 opens the renovated check-in lobby at the eastern end of Terminal 3.
Read the sequence as a calendar for corridor decisions. The 2027 phase adds reasons to arrive early and stay landside. The 2028 phase adds a lounge product that competes with a day room and a club floor. The 2029 phase rebuilds the first hour of the departure journey.
The gap in the submarket data
The airport publishes traffic, the programme and the shuttle roster, and it publishes no hotel performance series. No occupancy, average daily rate or revenue per available room figure for the San Francisco airport corridor appears in this record.
