At about 1,870 miles from Houston's George Bush Intercontinental Airport (IAH) to Seattle-Tacoma International Airport (SEA), a nonstop runs roughly 4h15, give or take with the winds. United Airlines carries all of the nonstop award space in the data. Aircraft logged on those nonstops include the Boeing 737-800 and Boeing 737-900. Expect mostly connecting results: only about 6% of the award options in the data are nonstop.
On a domestic run like Houston–Seattle, award prices go head to head with cash fares. The cheapest economy seat connects once; skipping the connection means an economy nonstop on United Airlines at a higher price. The economy floor adds about $6 in taxes and fees, in line with the route's typical economy taxes. Run the miles-or-cash math each time: a cheap fare usually beats spending points. Before moving bank points anywhere, confirm the seat is bookable, since transfers are one-way.
American AAdvantage wins economy at 10,000 points and first class at 34,500. Qantas Frequent Flyer takes business class at 43,600 points. For a cross-check, Alaska Atmos Rewards, Delta SkyMiles, and United MileagePlus price the route too. Partner pricing sets the business class floor, so the program and the airline flying the seat differ. No program wins more than two cabins here, so pick the seat first, then the currency.
United Airlines is the only airline with nonstop award space on Houston–Seattle in the data, and its Star Alliance membership opens that nonstop to partner programs beyond United MileagePlus. Off the nonstop, the cheaper connecting awards in the data route through Chicago. Only four airlines hold award inventory on the route, yet five programs price them, so the competition is between currencies more than carriers.
The data shows no same-metro alternate airports on either end of Houston–Seattle, so the main airports are the ones to watch. Pricing the round trip? Seattle to Houston is tracked separately, and awards can price differently each way. For another option from Houston, Atlanta prices from 25,000 points at last check.
