Seattle (SEA) tracks 25 destinations here, and the verified count, 13 of 25, breaks down almost entirely along two lines: all 9 U.S. domestic pairs are verified, and so are 4 of the 16 international ones — Vancouver, Calgary, and Toronto in Canada, plus London Heathrow. The remaining 12 international pairs, including Ottawa, Montreal, five of six UK cities, and all five Australian cities, carry no verified nonstop record.
Seattle reads as a strong domestic and near-Canada hub whose confirmed long-haul reach, in this dataset, narrows down to a single anchor: London Heathrow. That's a real, useful data point — Seattle does have documented widebody-class service to at least one major European gateway — but it also means every other transatlantic or transpacific pair tracked here, from Glasgow to Sydney, is a distance and time reference rather than a confirmed nonstop, and should be quoted as a connection unless current GDS availability says otherwise.
All 9 of Seattle's U.S. domestic pairs are verified, from a 1.3-hour hop to San Francisco up to a 5.2-hour run to Miami, with Atlanta showing the most historical carriers at 6.

13 of Seattle's 25 tracked connections carry a verified historical operating record: every domestic U.S. pair, three of five Canadian cities, and one UK route, London Heathrow — a solid domestic and near-continental footprint with a single confirmed long-haul anchor.
OpenFlights' historical route dataset records 8 carriers operating this city pair, flying Boeing 747-400, Boeing 767-300ER (winglets), Boeing 777. It's the best-served pair in Seattle's whole tracked network — still confirm current-day operation and schedule in your GDS before quoting, since this dataset reflects historical service, not a live timetable.

Replace xxx with the destination's own 3-letter IATA code from the tables above — the availability-check syntax itself doesn't change by destination, only the city pair does.
This reference tracks 25 city pairs from Seattle: 9 domestic U.S. routes and 16 international, covering Canada, the UK, and Australia.
Yes, one: London Heathrow, which carries a verified historical direct-service record with 8 historical carriers. The other 5 UK cities tracked here do not.
Vancouver, Calgary, and Toronto carry a verified historical direct-service record; Ottawa and Montreal do not.
Not in this dataset. None of the 5 Australian pairs tracked here show a verified nonstop record, and distances run 11,829 to 14,872 km, so plan these as connections and confirm current routing in your GDS.
Atlanta, at 3,505 km and about 4.1 hours, shows 6 historical carriers, the most of any Seattle domestic pair in this dataset.
