NOTICE: Winter Weather Diversion Busing in effect Nov 1 - April 15

Winter Weather Related Flight Diversions

AFTER APRIL 15: If for some reason a SUN flight is cancelled passengers will be assisted by local agents or they can call the airline's reservations # for help in re-accomodation on the next available flight.


Ah, winter - we sure love that snow, except when it affects air travel.  Occassionally winter weather will affect flights into and our of our airport (SUN). But if that happens, our community has a special diversion busing program in place that allows passengers to arrive and/or depart from an alternative nearby airport on the same schedule. If you are traveling to SUN this winter, please make sure you are informed about the diversion busing operations for your airline, which are outlined below.

We are continuing to collectively work to make the experience as pleasant as possible for SUN air travelers. And most importantly, you do get to your destination! We are very fortunate here in Sun Valley - there are only a few airports in the US where airlines offer this extraordinary level of service for travelers impact by weather. 


****MOST IMPORTANT! ****PLEASE ENSURE YOU HAVE THE CORRECT EMAIL AND CELL PHONE CONTACT INFORMATION (that you use while traveling) IN YOUR AIRLINE TICKET RECORD! This is what the airlines will use to alert SUN passengers in advance of a change in flight status and let them know what time to get to the SUN airport in Hailey to catch the bus transportation to Twin Falls or Boise airport if their outbound flight is going to be diverted to an alternative airport.  

INBOUND FLIGHTS TO SUN: If you are diverted on your inbound flight to an alternative airport, you will be provided with complimentary and comfortable motorcoach transportation to SUN.

  • Delta and United flights divert to Twin Falls, ID- 60 miles south of SUN

  • Alaska flights divert to Boise, ID - 150 southwest of SUN

OUTBOUND FLIGHTS FROM SUN:  CALL the local SUN Winter Operations Hotline for your airline at least 4-6 hours in advance of your scheduled flight departure to confirm flight and busing status. Please listen CAREFULLY to the information provided and plan accordingly. If your flight is being diverted outbound, you must get to the airport on time to catch the bus to alternative airport. Times will be provided on the message.                                  

Do not rely on airline schedule apps for flight departure information as they will not provide information on whether flights are being diverted.

You MUST call the local airline WINTER OPERATIONS HOTLINE listed below for SUN flight status and diversion busing details.

Planned Flight Diversions
Usually the flight diversions are planned in advance, as weather forecast or current conditions necessitate. In this case, complimentary motorcoach transportation is arranged for both in and outbound SUN passengers to the diverted airport, usually requiring the outbound SUN passengers to get to the airport in Hailey several hours in advance of their scheduled flight departure time. 

Unplanned Flight Diversions 
Unplanned diversions are when the flight attempts to land at SUN but is not ultimately able to do so and therefore must divert to an alternate airport. In this situation, the flight passengers will be accommodated with complimentary motorcoach transportation from TWF or BOI to SUN, but there is not sufficient time to get outbound SUN passengers on a motorcoach to TWF or BOI to catch the diverted flight without dramatically affecting that flight’s down-line connections, so those passengers will be accommodated by the airline on the next best available flight on either its own system or another SUN airline.

Flight Cancellations 
As can happen at any airport due to unforeseen circumstances (weather at down-line airports, mechanical situations, etc.) occasionally flights get outright canceled to or from SUN. If they do, the airlines will do their best to accommodate travelers on the next best available flight on any carrier the airline has agreements with, whether from SUN, TWF, or BOI.  Providing the best possible customer service to passengers is very important to our SUN airline partners.
