[San Francisco, July 8, 2026] — Travel plans were disrupted at San Francisco International Airport following the cancellation of two scheduled departures. The canceled flights affected a domestic service to John F. Kennedy International Airport (JFK) in New York and an international departure to Montréal-Trudeau International Airport (YUL) in Canada.

Although the volume of cancellations was limited to two flights, both flights operate on high-demand business and transit routes. The carriers involved, Delta Air Lines and Air Canada, utilized modern narrowbody aircraft for these services. Passengers scheduled on these departures faced rebooking processes or rerouting through alternative airline hubs.

Neither airline has issued a public statement clarifying the technical or operational causes for the cancellations. Schedule changes at major West Coast hubs like SFO are commonly driven by late inbound aircraft arrivals, crew duty-hour limits, or air traffic control flow programs in congested destination airspaces like the US Northeast.

Canceled Departures and Aircraft Details

The cancellations at San Francisco International Airport affected the following scheduled flights:

• New York JFK route (Delta Air Lines): Flight DAL691, scheduled to depart on Tuesday at 1:00 PM PDT, was canceled. The transcontinental flight was scheduled to operate using an Airbus A321neo (A21N).
• Montreal route (Air Canada): Flight ACA756, scheduled to depart on Tuesday at 8:00 AM PDT, was canceled. The international service was scheduled to use a Boeing 737 MAX 8 (B38M).

Data Table

San Francisco International Airport (SFO) Canceled Flights

Airline	Flight Number	Aircraft Type	Destination Airport	Scheduled Departure
Air Canada	ACA756	Boeing 737 MAX 8 (B38M)	Montréal-Trudeau International (YUL)	Tuesday, 8:00 AM PDT
Delta Air Lines	DAL691	Airbus A321neo (A21N)	New York JFK (JFK)	Tuesday, 1:00 PM PDT

Why This Matters

Our analysis of the flight data indicates that even a minimal number of cancellations on transcontinental and transborder routes can cause disproportionate passenger displacement. A flight like Delta's SFO-JFK service on an Airbus A321neo carries up to 194 passengers, while Air Canada's Boeing 737 MAX 8 carries 169. Together, these two cancellations displaced over 350 travelers on a single morning.

Because transcontinental routes between the West Coast and New York operate near capacity during the summer peak, finding immediate empty seats for 194 stranded passengers on subsequent direct flights is extremely difficult. Airlines are forced to reroute passengers through mid-continent hubs (such as Minneapolis, Detroit, or Toronto), which adds hours to travel times and occupies seats that would otherwise be available for other passengers.

Furthermore, Montreal Trudeau is Air Canada's secondary European gateway. A significant portion of passengers boarding ACA756 in San Francisco are connecting in Montreal to transatlantic flights bound for Europe. Missing the SFO-YUL feeder leg causes these travelers to miss their onward international flights, forcing the airline to pay for overnight hotel accommodations and rebook them on partner airlines.

Industry Outlook

Market trends suggest that carriers will continue to prioritize schedule reliability on high-yield international routes, sometimes sacrificing short-haul or transborder frequencies when crew or aircraft shortages occur. As airlines face ongoing delays in new aircraft deliveries from Boeing and Airbus, operational spare margins will remain tight. Passengers traveling on transborder or transcontinental flights should anticipate higher average ticket prices and consider booking morning flights to allow for same-day rebooking in the event of a cancellation.

FAQ

Which flights were canceled at San Francisco Airport? Two departures were canceled: Air Canada flight ACA756 to Montreal (scheduled for Tuesday at 8:00 AM PDT) and Delta Air Lines flight DAL691 to New York JFK (scheduled for Tuesday at 1:00 PM PDT).

What aircraft types were scheduled for these canceled flights? Air Canada scheduled a Boeing 737 MAX 8 for the Montreal flight, while Delta Air Lines scheduled an Airbus A321neo for the New York JFK flight.

How does a cancellation on the SFO-Montreal route affect international travelers? Many passengers on this route connect in Montreal to international flights bound for Europe.
