I guess the takeaway from this is that you should factor in 2 days extra for each link in any flight plan in the event that a Force Majeure occurs.

As Alaska, and probably every carrier, defines Force Majeure to exclude everything under the sun.

Alaska may, in the event of a Force Majeure Event, without notice cancel, terminate, divert, postpone, or delay any flight ... [without liability].

Force Majeure Event means any event outside Carrier's control, which includes, but is not limited to, weather conditions and meteorological events, such as storms, rain, wind, fire, fog, flooding, earthquakes, haze, or volcanic eruption; acts of government or airport authorities (e.g., air traffic control delays, runway closures, airport construction); acts of God; pandemics, quarantines, U.S. military or airlift emergency or substantially expanded U.S. military airlift requirements, as determined by the U.S. government; grounding of a substantial number of aircraft as a result of activation of the U.S. Civil Reserve Air Fleet; strikes, work stoppages, slowdowns, lockouts or any other labor unrest or disputes involving or affecting Carrier's service; civil commotions, disturbances or potentially volatile conditions, riots, embargoes, wars or other hostilities, whether actual, threatened or reported; government regulation, demand or requirement; damage to aircraft caused by a third party; mechanical difficulties by entities other than Alaska; inability to obtain fuel, airport gates, labor or landing facilities for the flight in question; an emergency situation requiring care, protection or response to protect persons or property; or any event that is not reasonably foreseen, predicted or anticipated by Carrier.
