live · updated 1h ago

OPS Watch · 110,241 legs measured · last 90 days · 1 route outbound only · 3 routes inbound only

134 nonstop destinations from Seattle–Tacoma International Airport, flown by 31 airlines. 130 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 129 routes with enough history show how reliably they actually run: on-time share and cancellation rate from the last 90 days. Right now departures are +27 min.
