AI175 Flight Status: Everything About the Air India Trip to San Francisco Today

Monitoring the AI175 flight status is a critical task for passengers traveling between India's technological hubs and the United States. As one of Air India's flagship ultra-long-haul routes, AI175 connects Bengaluru (BLR) and New Delhi (DEL) to San Francisco (SFO). This specific flight number often represents a multi-leg journey that bridges the Silicon Valley of India with the original Silicon Valley in California. Understanding the nuances of this flight, from its historical punctuality to the specific aircraft deployed, helps travelers manage their expectations for a journey that spans over 15 hours in the air.

The current route logic of AI175

AI175 is traditionally structured as a continuous service that originates in Southern India. Based on current operational data for 2026, the flight typically begins at Kempegowda International Airport (BLR) in Bengaluru. It serves as a feeder leg to the primary international gateway at Indira Gandhi International Airport (DEL) in New Delhi before making the trans-Pacific leap to San Francisco.

Leg 1: Bengaluru to New Delhi

The first segment of AI175 is a domestic hop within India. Departing from the modern Terminal 2 at BLR, the flight usually takes around 2 hours and 45 minutes to 3 hours to reach Delhi.

Scheduled Departure (BLR): Typically around 07:45 AM IST.
Scheduled Arrival (DEL): Typically around 10:30 AM IST.
Terminal Information: Passengers depart from BLR Terminal 2 and arrive at DEL Terminal 3.

This leg is essential for consolidating passengers from across South India who are bound for North America. While it is a domestic segment, the service is often operated by the same wide-body aircraft used for the international leg, providing a consistent cabin experience from the start.

Leg 2: New Delhi to San Francisco

After a layover in Delhi, AI175 continues its journey as a premier international service. This segment is where the flight truly earns its reputation as an ultra-long-haul marathon, covering approximately 7,700 to 9,300 miles depending on the specific flight path taken (often utilizing the Polar Route or the Pacific track).

Scheduled Departure (DEL): Typically around 12:30 PM IST.
Scheduled Arrival (SFO): Typically around 02:30 PM PST on the same day (due to time zone changes).
Flight Duration: Approximately 15 hours and 30 minutes.

Analyzing aircraft and cabin comfort: The Boeing 777-300ER

Air India predominantly utilizes the Boeing 777-300ER (B77W) for the AI175 service. This aircraft is the backbone of the airline's long-range fleet, known for its twin-engine efficiency and immense capacity.

Seating configuration

The aircraft assigned to AI175 generally features a three-class configuration: First Class, Business Class, and Economy Class.

Economy Class: Features a seat pitch of approximately 84 cm (33 inches) and a width of 46 cm. For a 15-hour flight, this legroom is standard for the industry, though the 3-4-3 layout in many refurbished 777s can feel tight for some passengers. Each seat is equipped with a USB port and a personal entertainment screen.
Business Class: Offers lie-flat seats which are indispensable for a flight of this duration. The configuration usually allows for direct or near-direct aisle access, though this varies depending on whether the specific hull has undergone the latest interior cabin refresh.
First Class: A small, exclusive cabin at the front of the aircraft, providing maximum privacy and enhanced meal service.

Technical specifications

The Boeing 777-300ER used for AI175 is powered by two General Electric GE90-115B engines, the most powerful jet engines in the world. This allows the plane to maintain a cruising speed of approximately 560-580 mph at an altitude of 31,000 to 39,000 feet. The aircraft is designed to handle the extreme temperatures and conditions found on the Polar Route, which is the shortest distance between Delhi and San Francisco.

Historical performance and punctuality

When checking the AI175 flight status, historical data suggests that travelers should prepare for potential variability. Punctuality on ultra-long-haul routes is susceptible to numerous factors, including headwinds over the Pacific, air traffic control congestion in Delhi, and ground handling efficiency.

On-time statistics

Recent data indicates that AI175 has a moderate on-time performance record.

On-time Departure Rate: Approximately 53%.
On-time Arrival Rate: Approximately 27%.
Average Delay: 44 to 46 minutes.

It is common for the flight to depart Delhi 30 to 60 minutes behind schedule. However, pilots can often recover some of this time during the 15-hour cruise if the jet streams are favorable. Arrival delays in San Francisco are frequently influenced by the heavy traffic at SFO during the mid-afternoon peak, where international arrivals from Asia and Europe converge.

Common causes for delays

Inbound Aircraft Arrival: Since the aircraft used for AI175 often arrives from another international or domestic destination, any delay in the previous leg cascades into the AI175 schedule.
Weather Conditions: Dense fog in New Delhi during winter months is a notorious cause for significant delays or cancellations. Similarly, heavy winds over the Pacific can extend the flight time by up to an hour.
Technical Maintenance: Given the rigorous demands of 15+ hour flights, Air India occasionally performs extra maintenance checks on the Boeing 777 fleet to ensure safety, which can lead to gate delays.

Passenger experience and amenities on board

Air India has been making efforts to modernize the service on the AI175 route. For a journey of this length, the soft product (food, service, and entertainment) is just as important as the seat itself.

Catering and meals

Passengers on AI175 can expect a minimum of two full meal services and one substantial snack service.

Main Meals: Usually offer a choice between Indian vegetarian, Indian non-vegetarian (often chicken or lamb), and sometimes a continental option. The Indian meals are generally considered the highlight of the service.
Refreshments: Mid-flight snacks, including sandwiches, masala tea, and biscuits, are available in the galleys or served by the crew.
Beverages: A full range of alcoholic and non-alcoholic beverages is complimentary in all classes.

In-flight entertainment (IFE)

The IFE system on the Boeing 777-300ER includes a selection of Bollywood blockbusters, Hollywood movies, regional Indian cinema, and television shows. While the hardware on older aircraft may feel dated compared to newer generations of entertainment systems, the content library is extensive. Passengers are advised to bring their own noise-canceling headphones for a better experience, as the provided headsets may not be of high fidelity.

Connectivity

As of early 2026, many aircraft in the Air India long-haul fleet have been equipped with Wi-Fi capabilities. However, availability can be inconsistent depending on the specific plane assigned to AI175 on a given day. Checking the aircraft registration via a flight tracker prior to boarding can sometimes provide clues regarding the onboard tech features.

Navigating the airports: BLR, DEL, and SFO

Effective travel on the AI175 route requires a good understanding of the transit and arrival airports.

Transit at Delhi (DEL) Terminal 3

For passengers coming from Bengaluru, the transit at Indira Gandhi International Airport is relatively straightforward as both the domestic arrival and international departure take place within Terminal 3.

Security: International-bound passengers must go through a dedicated transit security check.
Lounges: Terminal 3 hosts several lounges, including the Air India Maharajah Lounge and the Encalm Lounge. These are excellent places to recharge during the 2-hour layover.
Gate Information: AI175 typically departs from the 'A' or 'B' piers of Terminal 3, which are dedicated to international wide-body flights.

Arrival at San Francisco (SFO)

Upon landing in San Francisco, AI175 arrives at the International Terminal (Terminal I).

Immigration and Customs: Being a large aircraft, the influx of 300+ passengers can lead to long queues at U.S. Customs and Border Protection (CBP). Travelers with Global Entry will find the process significantly faster.
Baggage Claim: The baggage carousels for international flights are located on the lower level. It is advisable to check the monitor for the specific carousel number, as multiple large flights often arrive simultaneously.
Ground Transportation: SFO offers easy access to the AirTrain, which connects to the BART (Bay Area Rapid Transit) for travel into the city or to the rental car center.

Practical tips for AI175 passengers

Check Status Early: Use a reliable flight tracking service or the Air India mobile app 24 hours before departure. This helps in identifying if the inbound aircraft is on time.
Seat Selection: On the Boeing 777, the back of the plane can experience more turbulence. Seats over the wings (Rows 20-35) typically offer the most stable ride. For Economy passengers, seeking out rows with only two seats at the very rear (where the fuselage narrows) can provide extra side space.
Hydration and Health: The air in the cabin during a 15-hour flight is very dry. Drinking water consistently and moving around the cabin every few hours is vital to prevent Deep Vein Thrombosis (DVT).
Baggage Allowance: Air India is generally generous with baggage on US routes, often allowing two checked bags of 23kg each in Economy. However, verify the specific allowance on your ticket as rules can change based on the fare class.
Documentation: Ensure your US Visa (or ESTA) and passport are valid for at least six months beyond your stay. Having a printed copy of your return flight and accommodation details can speed up the immigration process at SFO.

Alternatives and comparisons

While AI175 is a convenient one-stop (or direct from Delhi) option, passengers often compare it with other carriers.

United Airlines: Operates a direct Delhi to San Francisco service. United's Dreamliner (787-9) offers lower cabin altitude and higher humidity, which some find more comfortable than the 777, though Air India often provides more competitive pricing.
Middle Eastern Carriers: Airlines like Emirates or Qatar Airways offer one-stop connections through Dubai or Doha. These involve a longer total travel time but are often praised for superior in-flight service and newer aircraft.
Singapore Airlines: Provides a connection through Singapore (SIN), which is a favored route for those who prefer the world-class transit experience of Changi Airport, despite the significant detour.

AI175 remains the primary choice for those seeking the fastest total travel time from India to Northern California, especially for those who prefer an Indian-centric service and food menu. By staying updated on the AI175 flight status and preparing for the unique demands of ultra-long-haul travel, passengers can ensure a smoother journey across the world.
