Check today: SFO to Valencia at $612

Delta’s September 12 post lists $612 Basic Economy (E class) or $832 Regular Economy (V class) round trip between San Francisco and Valencia, Spain. The sample itinerary runs November 10–17, 2026, with availability stretching from mid-October to early December 2026 and from mid-January to April 2027. Departures are valid Sunday through Wednesday, with returns Tuesday through Friday, requiring a Sunday stay. Tickets require purchase at least seven days before departure. 1

The flight routes through Paris Charles de Gaulle on SkyTeam partners Air France and Delta (SFO–CDG–VLC–CDG–SFO) with no stopovers allowed. Elite travelers earn $695 in Elite Qualifying Dollars on the itinerary. United States citizens travel visa-free for tourist stays. 1

The $220 gap between fare families warrants careful math. Delta’s Basic Economy fare excludes advance seat selection, bars flight changes and cancellations, and omits mileage earning. Adding checked baggage to Basic costs $85 each way, or $170 for the round trip. Paying $612 plus $170 in bag fees totals $782, placing the price just $50 below the $832 Regular fare. The Regular Economy fare includes a checked bag, an advance seat assignment, and standard change policies, making $832 the smarter purchase for travelers with luggage. 1

Check today: SFO to Geneva at $616

United’s September 13 post features $616 Basic Economy or $836 Regular Economy round trip in K class between San Francisco and Geneva, Switzerland. The sample dates are April 21–28, 2027, with travel windows open in November to early December 2026, January to February 2027, and April to early May 2027. Departures apply Sunday through Wednesday, and returns run Tuesday through Friday with a required Sunday stay. Bookings require at least seven days advance purchase. 2

The itinerary routes via Washington Dulles (SFO–IAD–GVA–IAD–SFO) with Star Alliance partners. United credits $705 in Elite Qualifying Dollars and 2,115 redeemable miles on eligible fares. United States passport holders require no visa for entry into Switzerland. 2

United’s Basic Economy restrictions eliminate advance seat selection, changes, and refunds, while withholding miles unless the traveler holds elite status or an eligible co-branded credit card. United charges $90 each way for the first checked bag on Basic transatlantic tickets. Two checked bags round trip cost $180, narrowing the actual cost gap between Basic ($796 with bag) and Regular ($836 with bag, seat selection, and changes) to $40. Travelers checking luggage gain substantial flexibility by choosing the $836 Regular fare directly. 2

Domestic corridor: Alaska SFO–Portland at $117

Alaska Airlines posted an autumn short-haul sale on September 7 offering SFO–Portland round trip for $117 Basic (X class) or $197 Regular (R class). Sample dates cover November 7–10, 2026, with availability extending through early December 2026 and from January through early August 2027. Tickets require purchase at least seven days before departure. 8

The route operates nonstop with 1,100 flown miles each way. Because the post is one week old, travelers should reprice the dates on Alaska’s booking engine before planning a trip. 8

The $80 difference between X and R class defines the choice. The $117 Basic ticket assigns boarding group last, disallows flight changes, prevents advance seat selection, and earns zero Mileage Plan miles. The $197 Regular fare includes standard seat selection, normal boarding, and full mileage accrual. Travelers carrying only a personal item and seeking pure transit savings can take the $117 fare, while those needing schedule stability should opt for $197. 8

East Bay snapshot: Southwest OAK–Long Beach from $96

Southwest Airlines displays one-way Basic fares from $96 between Oakland (OAK) and Long Beach (LGB) on its first-party route calendar.

Travelers wanting Choice benefits see $132 on November 7. Southwest collected these fare quotes within the last 24 hours. 3

Fares on peak September dates currently reach $335, giving the November $96 pricing an immediate $239 advantage over near-term flights. Travelers can book the November dates now with the confidence that Southwest points or flight credits remain reusable without penalty fees. 3

South Bay snapshot: Alaska SJC–San Diego from $79

Alaska Airlines displays Saver one-way fares from $79 between San Jose (SJC) and San Diego (SAN) on its route calendar, collected within the last 15 hours.

Reprice first: secondary European leads

Data boundaries and baseline disclosure

This issue incorporates verified cash and points opportunities from all three Bay Area airports: SFO, OAK, and SJC. The Oakland ($96 to Long Beach) and San Jose ($79 to San Diego) entries represent current first-party airline route-page snapshots with collection ages under 24 hours, rather than newly launched promotional flash sales. 3 4

The third-party flight deal sources for international routes provide specific fare rules, sample dates, and routing codes, but omit long-run historical average baselines. In place of an estimated historical average, this radar uses exact fare-family math: the $220 upgrade cost on Delta and United transatlantic routes directly measures the value of checked luggage, seat assignments, and ticket refundability. 1 2
