Cash fares from SFO
All nine deals below depart San Francisco International. No equivalent deals were posted for Oakland (OAK) or San Jose (SJC) in this cycle — see the OAK/SJC section at the bottom.
United: SFO – Singapore nonstop — $696 / $916
United's nonstop SFO–SIN runs 17+ hours and normally costs $1,200–$1,800 roundtrip. This window prices it at $696 in Basic Economy or $916 in Regular Economy — and the Regular Economy cabin includes two checked bags, which is unusual for a transcon-length deal at this price. 1
- Travel windows: mid-August to early November 2026; late January 2027; late February to March 2027
- Restrictions: Basic Economy has no seat assignment, no second checked bag ($100 to add), no changes or cancellations. A Sunday stay is required. Minimum 3 days advance purchase.
- Stopovers: Two permitted at $100 each (works for adding a Japan or Thailand leg)

SAS: SFO – Prague — $631 / $731
Scandinavian Airlines (SAS) prices SFO–Copenhagen–Prague at $631 Basic Economy or $731 Regular Economy, against a typical $1,000–$1,400 for this route. The $100 gap between tiers is worth paying: Regular includes one checked bag each way and advance seat selection; Basic has no bags ($75 each way if bought 22 hours before check-in), no changes, no cancellations. 2
- Travel windows: late August to early December 2026; late January to early March 2027

- Travel windows: November to early December 2026; mid-January to early March 2027
- Restrictions: Basic Economy has no seat assignment, no checked bags ($75 first bag, $100 second), no changes, no cancellations, and no mileage earning.

- Book at: Delta.com
Cathay Pacific: SFO – South China trio — $853 each
Three Cathay Pacific Q-class routings via Hong Kong all price at $853 roundtrip including taxes, against a normal range of $1,200–$1,600. Each permits two stopovers at $100 each — a Hong Kong stopover on one end costs $100 and converts a connection into a mini-break.
Visa note: Haikou (Hainan province) allows US citizens 30 days visa-free; Xiamen and Fuzhou require a standard China visa.
- Restrictions: Minimum 7 days advance purchase. Monday–Thursday departures and returns only.
- Book at: Priceline
Freshness warning: The Flight Deal notes that fares listed more than 2 days after the post date are often sold out. The Haikou fare was posted May 11; check availability before assuming seats remain.

Aer Lingus (which flies SFO–Dublin nonstop) is running a May Sale through May 15 with up to $425 per person off vacation packages.

Turkish Miles&Smiles: 30% off SFO→Istanbul awards — book by May 22
Turkish Airlines' Miles&Smiles program is discounting economy award tickets between Istanbul (IST) and nine Americas cities — SFO is explicitly listed. 16
The math: a normal SFO–IST one-way economy award runs around 45,000 Miles&Smiles miles. With the 30% discount, that drops to approximately 31,500 miles.
- Travel window: October 1 – December 10, 2026
- Booking window: May 11 – 22, 2026
- Transfer partners: Miles&Smiles accepts transfers from Citi ThankYou (1:1), Capital One (1:1), and Bilt Rewards (1:1)
- Turkish Airlines business class is frequently cited as one of the better business products in Europe, with notable onboard catering. If business class awards are discounted in your search, that's an added consideration.
Air Canada Aeroplan: SFO–Europe rates go up June 1 — book now
Aeroplan will raise partner redemption rates on June 1, 2026, regardless of when you fly. The current rates for SFO–Europe (6,001–8,000 mile distance band): 17
| Cabin | Current rate | Rate after June 1 | Change |
|---|---|---|---|
| Economy | 55,000 pts | 60,000 pts | +9% |
| Business | 85,000 pts | 90,000 pts | +6% |
| First | 130,000 pts | 150,000 pts | +15% |
Booking before June 1 locks in the current rates regardless of travel date. Aeroplan is a 1:1 transfer partner of Amex, Chase, Capital One, and Bilt. Rove also offers a 25% bonus to Aeroplan through June 6 — combining the Rove bonus with a pre-June-1 booking squeezes the most value out of your points. Aeroplan stopovers cost 5,000 additional points, which works well for multi-city European trips.
Flying Blue Promo Rewards: 18,750 miles to Europe — Bay Area note
Air France-KLM's Flying Blue is offering economy awards to Europe from select US cities at 18,750 miles one-way (normally 25,000) through May 31, book by May 31, travel through October 31. 18 19
SFO is not among the discounted US departure cities this month. The nearest discounted gateway is LAX, where KLM offers the 18,750-mile rate. Bay Area travelers could position to LAX (about 1 hour, Southwest fares from $59–$99 one-way from OAK or SJC to LAX) and then use the Promo Rewards from there.
With the Chase → Flying Blue 20% transfer bonus active through May 27, the effective Chase points cost drops to approximately 15,625 Chase points per one-way economy to Europe (18,750 ÷ 1.2). Business class Promo Rewards are available only from Saint Maarten (SXM) to Europe this month.
OAK and SJC — what's available right now
No dedicated low-fare deals were published for Oakland or San Jose departures this cycle from any of the sources tracked. The Flight Deal does not maintain OAK or SJC deal categories. Southwest is the exception: OAK → Las Vegas from $99 and SJC → San Diego from $59 (both one-way, Basic fare) are bookable today with no code required.
Alaska Airlines operates significantly from SJC and is running the 3-in-1 credit card offer noted above — that 50% discount code and 80,000 bonus miles are useful for SJC travelers booking future Alaska flights. Southwest is the primary low-cost carrier at both OAK and SJC for domestic routes.
