OPS Watch · 119,712 legs measured · last 90 days · 1 route outbound only · 1 route inbound only

138 nonstop destinations from Seattle–Tacoma International Airport, flown by 43 airlines. 136 of them also fly back in.

Measured from flights observed on Seattle’s own departure and arrival boards over the last 14 days. Every route below carries its observed weekly frequency, and 136 routes with enough history show how reliably they actually run: on-time share and cancellation rate from the last 90 days.
