You’re standing in the middle of Sea-Tac, coffee in hand, looking at the departures board for a direct shot to Upstate New York. I hate to be the bearer of bad news, but you won't find one. Honestly, it’s one of those travel quirks that catches people off guard every single time.
Despite Seattle being a massive tech hub and Rochester housing everything from the Mayo Clinic (the Minnesota one, but stay with me) to a major university and tech scene of its own, there are currently no nonstop seattle to rochester flights. You’re going to have to embrace the layover.

But here’s the thing: how you handle that layover determines whether you arrive in Rochester feeling like a human being or a crumpled-up piece of loose-leaf paper.
The Layover Landscape: Where You’ll Actually Land
Since you’re forced to stop, you might as well pick the airport that doesn't make you want to scream.
Most people just click the cheapest option on a search engine and end up sprinting through Chicago O’Hare (ORD) with ten minutes to spare. Don’t do that. Chicago is the most common connection point for this route—about 61% of travelers end up there—but it's also a weather gamble. If you’re flying in January or February, a Lake Michigan snowstorm can turn your one-hour layover into a twelve-hour airport floor nap.
Delta usually runs the show here with connections through Detroit (DTW) or Minneapolis (MSP). If you can snag a Detroit layover, take it. It’s one of the easiest airports to navigate in the country, and that indoor tram is a lifesaver. United will likely pull you through Chicago or Denver, while American loves Charlotte (CLT) or Philadelphia (PHL).
Southwest is the wild card. They fly into Rochester’s Frederick Douglass International Airport (ROC) too, usually with a stop in Baltimore (BWI) or Chicago-Midway (MDW). The "bags fly free" perk is great, but remember you’ll be doing the "Southwest Scramble" for seats twice.

Pricing Reality: When to Book and What to Pay
I’ve seen tickets for this route swing wildly. One day it’s $260 round-trip; the next, it’s $800 because a specific weekend in Rochester is booked solid for a university commencement or a festival.
Generally speaking:
- The "Sweet Spot" Price: If you find a round-trip ticket for under $300, buy it. Don’t wait.
- The "Ouch" Price: Anything over $550 for economy is pushing it, unless it's a holiday week.
- Cheapest Months: Data usually points toward February or September being the most budget-friendly. June is surprisingly expensive, likely due to the graduation season at the University of Rochester and RIT.
One little-known trick? Look at flying into Buffalo (BUF) instead. It’s about a 65-mile drive from Rochester. Sometimes the price difference is over $150, which more than pays for a rental car or a very long Uber.
The Flight Duration Trap
On paper, the distance is about 2,200 miles. A direct flight would be roughly five hours. But because of the layovers, your "travel day" is rarely shorter than seven and a half hours.
I’ve seen "optimistic" itineraries that claim a six-hour total travel time. Those usually involve a 35-minute layover in a massive airport.
Pro tip: Do not book a connection shorter than 50 minutes. Seattle to Rochester flights are notorious for small delays on the first leg. If your flight out of SEA is 15 minutes late—which happens constantly during the morning fog—you’ve just missed your connection to Rochester, and the next flight might not be for another six hours.

What to Expect at the Airports
Sea-Tac (SEA) is a beast. If you don't have SEA Spot Saver, you're doing it wrong. It’s a free service that lets you reserve a time in the security line. It’s basically a FastPass for the airport. Use it.
When you finally land at Frederick Douglass Greater Rochester International Airport (ROC), things are much smaller and quieter. It’s a very manageable airport. The car rental counters are right there, and you can usually get from the gate to the curb in under 15 minutes.
Making the Trip Suck Less
Since you're looking at a medium-haul journey with a stop, comfort is everything.
- Hydrate in Seattle: The air on those planes is drier than a tech manual. Drink a full bottle of water before you board.
- Download your maps: Rochester is easy to drive in, but there are some weird "inner loop" legacy exits that can be confusing if your GPS glitches.
- Check the Terminal: If you’re flying Alaska but the flight is "operated by" someone else, double-check your gate. Sea-Tac’s North Satellite is a long haul from the main terminal.
Actionable Steps for Your Trip
- Set a Price Alert: Use a tool like Google Flights or Kayak specifically for the Seattle to Rochester route.
- Check Buffalo (BUF) as an alternative: If ROC prices are insane, BUF is just an hour away.
- Aim for Detroit or Minneapolis: These are much more reliable connection hubs than O'Hare for winter travel.
- Reserve your security spot: Use the SEA Spot Saver five days before your departure to skip the morning rush at Sea-Tac.
- Avoid the 30-minute layover: Give yourself at least an hour to account for the inevitable Pacific Northwest departure delays.
