Wine Country weekends from the desert start earlier this fall. Palm Springs International Airport says Alaska Airlines will resume its seasonal nonstop to Santa Rosa’s Charles M. Schulz Sonoma County Airport on September 10, 2026, more than six weeks sooner than last season’s late-October launch.
The route will run five days a week, daily except Tuesdays and Wednesdays, through April 25, 2027, on Alaska’s 76-seat Embraer 175. Tickets are already selling on Alaska’s site, which shows September 10 departures in the booking calendar.
- Start date: September 10, 2026, about six weeks earlier than last year.
- End date: April 25, 2027.
- Frequency: Five days weekly; no Tuesday or Wednesday flights.
- Aircraft: Embraer 175 with 76 seats.
- Airports: Palm Springs (PSP) and Santa Rosa Sonoma County (STS).
Why the earlier start matters
Last season’s Palm Springs to Santa Rosa service began in late October. Moving the restart to mid-September opens more of harvest-season Wine Country to Southern California travelers who want cooler evenings without waiting for winter schedules.
According to Palm Springs International Airport, the earlier return reflects strong demand from the inaugural season and fits a broader pattern of airlines stretching seasonal service beyond the traditional winter peak.
Airport interim executive director Victoria Carpenter said travelers embraced the route and that PSP wants more seasonal and year-round choices from the hometown airport. That framing is useful for planning, even though fares and loads will still set how long the earlier start sticks in future years.
What the schedule looks like
Expect five weekly round trips rather than a daily year-round link. Skipping Tuesdays and Wednesdays is typical for leisure-heavy California routes where weekend and long-weekend demand dominate.
Alaska’s booking tool already lists September Palm Springs to Santa Rosa options, and NBC Palm Springs reported the same September 10 through April 25 window, independently confirming the earlier restart beyond the airport release. Treat published times as planning baselines and recheck close to departure for any aircraft or time tweaks.
Flight time is roughly under two hours gate to gate, far shorter than the drive up the Central Valley when traffic stacks on Interstate 5.
Who this route serves
Desert travelers headed to Sonoma County vineyards, the Sonoma Coast, or redwood day trips get a one-seat hop instead of a LAX connection. Santa Rosa travelers bound for Coachella Valley resorts get the reverse.
Connecting beyond Santa Rosa still depends on ground options once you land. PSP remains the desert hub; STS is the Wine Country front door, not a large connecting bank.
Deep Arrival’s things to do in Palm Springs guide helps frame the southern end of the trip if you are building a dual-city itinerary around the new dates.
How this fits Palm Springs’ fall network
The airport release notes other earlier fall nonstops as well, including Houston, Boise, Minneapolis, and Austin. Those extensions sit outside this Alaska Wine Country decision, but they show the same all-season push.
United’s year-round Palm Springs to Los Angeles service, announced earlier in 2026, is a different product aimed at LAX connections. Do not confuse that hub hop with the Sonoma nonstop.
Travelers comparing airline apps should book the Alaska PSP to STS market directly rather than assuming every Palm Springs fall route uses the same carrier.
Ground connections and trip shape
Santa Rosa sits inland from the coast, so build time for a rental car or rideshare if your real destination is Healdsburg, Sonoma, or the coast near Bodega Bay. A tight evening arrival can burn the first night if you still have a 45-minute road transfer ahead.
From Palm Springs, travelers coming from Palm Desert, La Quinta, or Indio should budget airport road time in both directions. The Embraer turn is short in the air, but Coachella Valley traffic to PSP still matters on Friday afternoons.
Hotel packages that advertise Wine Country access from Southern California often assume a car. Pair the Alaska ticket with a realistic ground plan before you lock nonrefundable nights.
If you prefer not to rent a car, confirm shuttle options between STS and your hotel district before purchase. Not every property runs airport transfers on the same days Alaska flies.
Business travelers using the route as a same-day hop should watch the five-day pattern closely. A Monday meeting in Santa Rosa with a Wednesday return does not match the published skip days.
Booking checklist before September 10
Decide whether a Thursday through Monday pattern fits your trip. Midweek stays may require an overnight elsewhere or a drive if you need Tuesday or Wednesday arrivals.
Confirm bag rules and seat maps on the Embraer 175, which is smaller than mainline narrowbodies. Families with car seats or golf bags should check aircraft limits early.
If harvest festivals or hotel weekends fill Sonoma County fast, the earlier flight start is only useful if lodging still has rooms. Pair the ticket search with lodging before celebrating the schedule win.
Keep an eye on weather and wildfire season advisories in both deserts and wine country as September approaches. A nonstop does not erase smoke, heat delays, or last-minute aircraft swaps on the regional fleet.
Travelers who need wheelchair assistance or gate-check gear should request help at both PSP and STS, which are smaller than Los Angeles International and usually move people faster once on the ground.
If September heat still hits the desert hard, morning departures from Palm Springs can be more comfortable than late-afternoon turns when ramp temperatures peak.
Compare total trip cost against a one-stop itinerary over San Francisco or Los Angeles before assuming the nonstop wins. When fares spike, a connection plus a shorter desert drive can still be cheaper even if it costs more time.
Also watch bag fees and seat selection on the Embraer. A free carry-on policy does not erase the smaller overhead bins, and golf or wine shipments may need checked-bag planning that a bigger aircraft would forgive.
Seasonal routes can thin or end early if loads disappoint. Keep flexible lodging where you can until after the first weeks of September confirm the earlier start is holding seats.
| If you… | What to do |
|---|---|
| Want Wine Country in mid to late September | Book Alaska PSP-STS from Sept 10; prior years waited until late October. |
| Need Tuesday or Wednesday flights | Plan around the five-day pattern or choose another gateway. |
| Are connecting beyond Sonoma | Budget ground time after STS; this is not a big hub bank. |
| Prefer LAX connections instead | Use year-round PSP-LAX options separately from this Wine Country hop. |
| Travel through April 2027 | The seasonal window is announced through April 25, 2027. |
- Mark September 10: That is the new seasonal restart, not late October.
- Avoid Tue and Wed assumptions: The route skips those days.
- Book lodging with the ticket: Earlier flights only help if rooms remain.
- Recheck Alaska.com: Times and fares can move before the first departure.
For Southern California travelers who missed last year’s late start, the September 10 return is the practical change: same Wine Country nonstop, an earlier calendar, and the same Embraer regional gauge.
